Unable to boot (usually), if boot successful do not have Taskbar

Q: Unable to boot (usually), if boot successful do not have Taskbar

Hello all,

First-of-all, thank you for reading this thread...any help you can offer is greatly appreciated.

I have a Dell Dimension 8400 (circa 2006?). Not used very often. New 1 TB hdd placed approximately 1 year ago. Since it was still running slow (about 6 months ago) with occasional BSOD, took it in to local "tech guy" who added some RAM, "cleaned things up", and replaced XP Home with XP Pro....

Since then, it has been working OK (minor problems not worth mentioning here)...only used for Quicken, Rhapsody, and very light internet surfing...NO questionable websites...have ZoneAlarm firewall and AVAST antivirus...

PROBLEM showed up last night...BSOD...on rebooting, following message comes up...
The instruction at "0x77c47e9f" referenced memory at "0x00000000". The memory could not be "read".

Click on OK to terminate the program
Click on CANCEL to debug the program
Regardless of which option I choose, the computer offers the same message again once or twice. After 8 to 10 minutes, my normal desktop appears. Unfortunately, there is no START or Taskbar. Whether I do anything or not, after 2 to 3 minutes, I get the following message...
System is shutting down...initiated by NT.AUTHORITY\SYSTEM

Windows must now restart because the Remote Procedure Call (RPC) service terminated unexpectedly.
I read that I should do the following ....reboot and press F8...I was given alternative reboot options...choosing either SAFE MODE or SAFE MODE WITH PROMPT or Reboot into Last Known Good Configuration all yield the same...normal desktop screen with no Taskbar...and then 2 minutes later, computer automatically shuts down (same message as above)...

I am not able to download HijackThis, DDS, etc because I can't open any browser...

Lastly, the computer seems to be stuck in a loop...it reboots then automatically shuts itself down...and then automatically reboots again...

NO, unfortunately, I do not have the 300GB of music and junk backed up...I had been emptying out a Power PC hdd onto this computer in order to take the Power PC in for "updating"...

Thank you, in advance, for any assistance you can provide....

Preferred Solution: Unable to boot (usually), if boot successful do not have Taskbar

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)


I have in my possession a hard drive with Windows XP Pro 64-bit. The OS resides on an NTFS file system partition of half of a 500 Gig hard drive. It is part of a custom built system and has had only been formatted once. This installation has been active for about six months. It did encounter a virus which infected the System Restore files and thus were cleared via safe mode. Since that time Safe Mode has been inaccessible. Consistently stopping at the acpitabl.dat file.

However, when booting Windows normally, the system boots with proper speed and with no apparent issues and continues to work for days on end.
It is only when booting into Safe Mode that any issues become apparent.

I am curious as to any solutions this fine community may have to offer. I received great information from the Hardware group and hope for the same here.

System hardware includes:
AMD Phenom Quad AM2+ Black Edition
Gigabyte MA790GP-UD4H
G.Skill Memory
Corsair 1000W PSU
Windows XP Pro x64

Hey,I really need some help with the following issue: Details:HW: Y520 with 16GB RAM, GTX 1060, SSD (GPT) + HDD (MBR)SW: Win10 pro - including latest updates. On GPT based SSD and in UEFI mode.BIOS: latest one is loaded Problem:In short; The FIRST boot each day is unsuccessful, but the SECOND right after the failed attempt is always successful. More details:This also happens, if I switch the notebook on after not using it for a few hours, like 3h<So during the first attempt the notebook is just freezing and and I have to press and hold power button. The last thing I can see is the lenovo logo and the stopped spinning circle animation. Notebook doesnt react to ctrl+alt+del.The strange thing is that right after these 1st attempts the 2nd boot attempts are always successful, windows10 loads in and no problem after that. What I already checked:-Windows event viewer: There are no records from the failed boot, I guess because windows is not even loaded.-Drivers: All drivers are installed-BIOS: I didnt see any related setting. The OS was installed in UEFI mode and bios is set this way (UEFI)-I run all the quick and deep hw diagnostics test on lenovo support page - No issues.-Win10 reinstall: Even after a clean install the freezes are still happening. Installed win10 twice but no change, still freezing.What causes the freezes!?If needed I can make a video as well.Thanks in advance!

I have an odd problem, but will start slow with the weird behavior rather than giving a lot of detail at first. If more is need, feel free to request. Hopefully the issue is apparent from the main symptom.

Sequence of events

1.Dual boot (win7 / win 8.1) - previously working - both on SSDs. Using Easy BCD on both OSs
2.Recently change mobo battery (worked fine immediately after change other than having to re enter bios boot order)
3.Shut down computer to sort cables behind. Switch off Power supply before pulling cord
4.Started having boot issues again. The following screen appears (sometimes the black one shown in attachment, sometimes blue with white text)
5.ctrl-alt-del on screen leads to successful boot (choice of OS comes up)

BIOS boot takes about 3 minutes to complete its tasks with the Intel logo displayed. No beeps. Then Windows XP-SP2 boots normally and works fine.

The different BIOS steps are not displayed on the screen any more: no BIOS parameter setup option, no Windows boot option (we set a waiting period of 15 seconds).

We ran a Passmark BurnInTest and the only failure pointed out was a defective NVIDIA GEForce PCX 5300 graphic card. Driver is recent (May 2008, vers. XP Control Panel Device Manager indicates that the driver is working fine.

Win 7x64
Everything seems to be working fine, but as the title suggests, when i tap F8 the Advanced boot options DO appear, but when i engage "Repair Windows" it just goes into a normal boot. Ive tried booting from my installation CD that i've purchased from Acer, but does nothing. And Yes My CD Drive is working, as well having this set as top priority in BIOS and CD is in good condition.

In addition to this, ive tried using the "Advanced Recovery options" from within Windows itself but when i go to click restart computer, i get an error message, with red-x, stating windows is unable to restart.

Additional info that may be relevant, is that a few months ago, i had a friend work on my computer, because windows wouldnt boot at all. When My laptop was returned to me, everything was fresh, but there was missing programs etc...He said, he had to format the hard drive to get it up and running again.

Anyway i appreciate any help as to what i should i do next, or answer any questions you may have-Thank-you!

Hoping someone can assist.

I helped a friend out recently by reinstalling Windows XP on his laptop. As part of that we also used an air can cleaner to clean out the vents and found they were so clogged (cat hair mainly) that we got the vacuum out too and masses of dust and hair came out.

Anyway, things seems fine however the Laptop when switched on starts to try and boot several times, usually half a dozen attempts each time getting no more than a couple of seconds into the boot process but keeps retrying to boot-each time a clicking noise can be heard as it switches itself off and tries again. When it does finally boot it works fine (and the clean up has stopped its overheating issue).

Could we have caused more damage by the vigourous cleaning of the vents and fans that could cause this boot up issue? Loosened something maybe or dislodged dirt, dust or hairs which are causing a short or something.

Any help greatefully received please.

Hello! I am hoping for just one more successful boot from my hard drive so I can back up to external media. Just one!

In the past wehn I have had booting problems, "chkdsk /r" and/or "fixboot" has solved the problem. I am now unable to boot from the hard disk in any mode or config. When I run Dell Diagnostics I get a "Pass" grade on my hard disk so I am hopeful that means it is not totally hosed.

Additonally, I have tried the "bootconfig /rebuild" option. The blue screen error of death I receive is as follows, "STOP: c000021a {Fatal System Error}...The Windows Logon Process system process terminated unexpectedly with a status of 0xc0000034 (0x0000000 0x0000000)....The system has been shutdown"
Is the "fix mbr" command a viable option at this point? I get an ominous warning about potential partition damage when I try to execute it so I have been reluctant to do so thus far. I would greatly appreciate any ideas out there.

Windows 7 64-bit.

This problem is the same or similar to another I found searching here but no details on the resolution of that one are available. http://forums.techguy.org/windows-vista/609177-blank-screen-when-starting-windows.html

I have no text or mouse cursor. The computer appears to boot successfully; I just can't see anything.

The computer had been running fine and I left it on. I came back a few hours later I noticed it had powered itself off. When I powered it back on the next day, I get BIOS startup info (normal) and the animated "Starting Windows" screen (normal) then black screen (not normal).

Windows update is enabled but set not to install automatically so the shutdown was unexpected.

I am running Norton system protection.

In black screen failure more, I see occasional disk activity as I would expect when booted normally. I am able to access network shares on the machine from another computer connected to the home network.

I get the same symptom in all of the safe mode startup options including command prompt and 640x480.

The recovery console does work (no black screen there) but I've tried the testing and restore options there with no luck.

I've tried swapping out the display card. Same symptom with a similar card.

I've disconnected all devices except mouse, keyboard and display.

For an unknown reason (my guess is an update was automatically applied and automatically restarted), my computer rebooted overnight and in the morning was stuck in a failed boot loop.  When trying to boot I get the message:
"Preparing to configure windows"

"Do not turn off your computer"
Then after a few seconds the computer reboots and does the same thing.  Safe mode yields the same result.  Using the F8 option to restore last known good configuration doesn't change anything.  I can boot into the recovery console.
I have tried running SFC /SCANNOW in a command prompt in the recovery console and get the message:
"There is a system repair pending which requires reboot to complete. Restart Windows and run sfc again."
Restarting of course doesn't change anything.  So it seems something happened to an unfinished update and is still pending.  I think if I can remove this pending update I might be able to boot normally, or at least run SFC and hopefully then boot
Does anyone know what I should try to remove this pending update that appears to be preventing a successful boot?

I took the source SSD from machine A and a target SSD from machine B and put them in a duplicator and successfully ran that process. I pulled the target SSD from the duplicator and inserted back into the machine from whence it came, fired it up and it it whirred to life... "Getting resources ready" passed. "Region/Language" passed. At the "Customize settings" screen I have used both the "Express settings" and customized the options available. When I click next it goes to a black screen, thinks for 5 seconds, and then reboots back to the region selection screen.

Nevertheless, she gets home and we've got dead video on the device.

Hi there, firstly just want to say thank you to this forum - I'm newly registered but have followed a lot of advice here to fix machines in the past. Registering now as I need some advice of my own! Sorry for the long post, I just want to be as clear as possibly as I the computer is at my parents' house and my dad might need to run some tasks for me.
In summary:
My computer won't boot XP due to a missing/corrupted hal.dll error, which appeared after a successful boot. The machine hadn't been run for few years and the CMOS battery was flat. After setting the clock in bios it booted to XP fine, then produced error after 5mins. Puppy Linux mounted the drive but was too unresponsive to actually use. Ubuntu live cd won't mount the hard drives, giving exit code 13. My goal now is data recovery - I'll probably try to reinstall Windows or dual boot Lubuntu afterwards.
More details:
I've read lots about my error but nothing given how it appeared I need some advice as I don't want to damage the drive (I just want to recover the data before setting up a new dual boot config). Further details and steps below just in case it helps to isolate the issue, as I've read some people saying that the problem won't be with hal.dll but the boot.ini file (which I'd find odd as it did boot just like it used to). Additionally, whilst the error message said windows could not start, the message was the same when it did boot as well as when it couldn't. Is it just that the drive is still mounted in wind...

A:hal.dll error after successful boot, CMOS battery flat

hal.dll is a very system specific file that is chosen from a selection of identically named files in the installer, especially for your setup, and then modified on on first run. You cannot replace hal.dll. An error with this file is one of the few instances where a reinstall is the only option.
Do not run chkdsk, it's likely to scramble your drive if it's not mounting properly and if there is a physical problem with the disk you may cause it to fail completely. Mounting it on another running Windows system and then copying your data over is another option that is worthwhile as Windows can sometimes handle NTFS better than Linux.
Failing that... you are right adding Testdisk to your list of options. That would be the next step..

Computer: HP Pavilion DM4 3070-se (Beats Edition)
OS: Windows 8

Hi all,
Beginning last night I had some problems with my computer. It would not boot up, and when I started it the BIOS showed a '3F0 hard drive not exist' error. I left it until this morning, and tried again. Everything booted up and it reached the Windows 8 login screen -- I have automatic login enabled, but the screen freezes (spinner indicator stops suddenly) and the screen goes black. It restarts again, and sometimes I get the Win8 repair screen, sometimes I get the 3F0 error again.

The inconsistency makes me think that something is screwed up hardware-wise, but I'm not totally sure. Apparently, from reading online, the problem could be the HDD (I don't think this is the case) or a poor cable connection (most likely), or a software problem.

Because I don't have recovery media for Windows 8 (I installed it on a USB drive I don't have with me) I can't try a system refresh or restore, but I'd rather avoid those if at all possible.

Do you all think that a good option might be to take it to a hardware repair place and have them check the cables for errors? Or is this something I should try to fix by myself? Thanks!


A:hard drive problem preventing successful boot

Why do you think that this isn't the hard drive? IMO that'd be the first thing that I'd suspect.
Most HP's have hardware/hard drive diagnostics built in. Try pressing and holding the "Esc" key when you turn the system on - it should give the option to logon to the diagnostics.

If it is the hard drive, it may not work (as the diagnostic tests are loaded on the hard drive) - so you'll have to try booting to a hard drive diagnostic (such as those here: Hard Drive Diagnostic Procedure ) If you have trouble booting to a hard drive diagnostic, post back and we'll try to help you through that.

If the system is under a year old, it's likely still under warranty - so please ask (at the place where you purchased it) how to get repairs done under warranty. The warranty will cover hardware problems but not software problems (and they should be able to do the hard drive diagnostics there).

Good luck!

I recently upgraded some of the hardware on my laptop (keyboard, hinges, memory), and laptop was working like a charm. The very next morning (laptop stays on at all times), the screen had gone black and the computer could not be rebooted. I do not know if the system did an automatic update overnight before the mysterious black screen appeared, but it is possible. Failure occurred on January 13, if that helps.

When I try to boot, I get a Dell splash screen and a successful POST, but at the point where it should hand off to the OS the screen goes black -- no Windows logo or hard drive activity.

I have tried replacing the hard drive, including a fresh installation of XPSP2 from the Dell CD. Drive formatted successfully and copied over all files, then had disk read error on restart. I have purchased a USB connector for the hard drive and was able to read and backup original drive using a different computer. New drive also appears fine (though it is 320GB and system only recognizes it as 137GB). Tried repartitioning new drive with 120GB partition (using other computer), booted from WinXPSP2 CD, and black screen appears after "Windows is inspecting your hardware".

I have tried replacing the boot.ini, ntdetect, and ntldr files on the original hard drive and tried using a boot CD (laptop does not have a floppy drive), but still get the same black screen.

Hello there,

I have a problem. I have a dual boot computer with Xp on C: and Win2k3 on D:

As my XP is behaving very weird lately, I intend to reinstall my C: again with XP again. But if I do so, my Win2K3 on D: will fail to start. I have done this experiment on a spare machine.

Does anyone know how I can reinstall XP on my C: and yet make sure that my Win2K3 still works well on my D: ?

Any help is greatly appreciated.

A:Win2K3 unable to boot after installing WinXP as a dual boot

Yes. You need to restore the boot environment that was installed with Windows 2003 server. Its more up to date than the one that was installed with XP, and is capable of booting both, whereas the older XP one you now have can only boot XP and not 2003.

I believe you will be able to get round this:

Install XP.

Backup your boot.ini file.

Boot from your Windows 2003 CD and begin an installation.

After the text based stage, where the files are copied to the hard drive, STOP THE INSTALLATION BEFORE THE GRAPHICAL STAGE, AND DON'T FORMAT!!!! You can do this by booting from the Windows 2003 CD instead of the HDD.

Then, boot from the Windows 2003 CD into recovery console, and rename your old boot.ini file as the new one.

Basically, you are wanting the Windows 2003 installation program to write its boot environment to the HDD again, but not to reinstall the OS.

You get around this in future by installing OSes in the order they were released, from the oldest to the newest, so that the following would be installed in this order:

Windows 95
Windiws 98
Windows NT 4
Windows 2000
Windows XP
Windows 2003

I hope this helps. Sorry if this is a little vague but its early in the morning. Post back if you still have questions, but I've encountered this problem many times and that was how I fixed it. I don't recall fixboot or fixmbr from the recovery console helping.

I'm assuming that you are currently communicating from another computer.
Do you have the installation disk? If not, then the trip to the PC wizard sounds like a wise choice.
The data loss will depend on what is wrong and when you made your last backup. It could be very little to total.

So I recently got some laptop parts to upgrade my laptop with from my friend who had the same model. Everything was working until I switched the harddrive (Big mistake). I thought since the model of laptops was the same, it could just be swapped in, but I was wrong and now I can't completely bootup my laptop with either drives. (I'm currently trying my fixes on my original drive)

On a restart after it downloaded some drivers, the device scanned the harddrive for consistency which deleted a few things. Since then it is mostly unable to boot (there have been a few times that it booted up but they are few and eventually they shut itself back down) and throws me in a bootloop even after I switched the original harddrive back in. I can boot it up successfully into safemode and use my windows recovery disc to boot up my laptop but neither of those are permanent fixes.

I've tried using the built in startup repair multiple times but it says it is unable to fix the problem. Looking at the logs of the scan, it says the root of the problem is a corrupt system volume disk.

I've also tried using system restore to earlier time but no luck. I've tried last known good configuration but didn't work.

I've tried performing a chkdsk function which was not able to fix the problem.

I've tried using bootrec. one of the functions showed that I had 0 windows installed. looking up and following the /rebuildbcd function from the microsoft site I fixed that problem so that it shows ... Read more

When I start the machine (XP Pro), it wonít boot in any mode. Going via F2 I can get to boot from CD but I donít have an XP recovery CD for the machine as it was an OEM with pre-installed XP (Tried a friendís XP Pro Recovery disc but it just gets me to Unmountable Boot Volume)

Have run Ubuntu (which works) and have recovered my files but would like to recover the XP OS if possible. Is there any way I can use Ubuntu to recover (as the HDD is obviously ok). Sorry havenít got any info re the machine apart from its a Toshiba U400.

Any thoughts would be really appreciated

Having problem with son's HP desktop.  When it boots, press the Esc key, get a boot menu. But ... unable to select ANY of the items.  Keyboard is not recognized when in this menu. Tried several different keyboards -- same symptoms on all. Also, despite having the CD/DVD device first in the boot order, when have bootable CD or DVD in the drive, see the text come up to press a key to boot from that device, but it does not boot from the disk, instead it puts up a message about booting from the system -- and once again, the keyboard(s) appear to be nonfunctional at this point. Product number: XX094AV Looked on the HP site to see if there is a BIOS update, but there is no BIOS listed. Could use some help on this. thanks

Hey all.
This is probably the biggest problem i've encountered with windows ever and i actually suspect its my hardware but not sure how to prove it and what step to take next if it is.

I have w7 installed on a SSD 64gig (C ) and most of my apps/games etc on a standard 1tb HDD (E )

The problem:
-as of yesterday, on starting the computer, windows 7 fails to boot, it goes to the w7 splash screen for about 15secs and then the monitor flickers off and the system restarts. W7 then gives the option to start normally or in repair mode.
-I've gone through repair mode now and tried both the startup repair (9 times, it finds no specific problem),
-the system restore, which lists 3 possible restore points (each one says success but then the same loop as above occurrs anyway)
-Ive also tried the bootrec commands via the command prompt available in system recovery.
-When i try to boot in with safe mode it goes black with a cursor and stops there
-when i try to boot via the dvd, it loads the windows background and cursor and stops there.
-In safe mode via the dvd it loads black screen and the 'safe mode' text in each corner and white cursor and stops there.

so at the moment i can't actually even do a repair or even clean reinstall via the disc which is pretty disturbing.
I've also tried chckdsk and used chkdsk /fix. this did report problems on the C drive and the /f run did say it corrected things on the ssd but still i am unable to load or boot via safe/system recover or ev... Read more

A:Win7 boot failure, DVD unable to reinstall/boot


All these symptoms point to a hardware issue to me as well. In particular, the part about the monitor flickering off draws my attention, because I wonder if it is a video card problem.

Do you have another graphics card you can use? If you are using a real video card, use the onboard graphics to test with if you have them.

The problem about which I'm posting is with a Gateway 820gm XP Media Center 2005 PC. Some background information on the state of this PC before the incident:The system's main hard drive died last week (no mystery, I dropped the friggin' thing), so I recently put in a new HD and reinstalled the operating system. After many hours downloading all of the Windows Service Packs and other updates (the most recent of which was the Office 2007 Compatibility Pack), the PC was finally back up and running, and was doing so quite smoothly.I typically leave my PC on overnight and use an alarm clock program to wake myself up. When I awoke to my cell phone alarm instead, I noticed the usual signs of a power outage. (12:00 blink on microwave, stereo, etc.) Naturally, I switched on my computer. Then...The computer began to boot as normal and prompted me for the boot password, which it took as expected. It then continued to the usual Windows splash screen that precedes the Welcome Screen or the Desktop (depending on user settings). However, after the Windows splash screen, my monitors remained blank. After several minutes and, wondering if this was just a display failure, I began to take actions that would normally result in sound output (activating Windows Media Center, keying Shift 5 times for the StickyKeys beep, etc.) No result. I tested the "sleep" button on my keyboard which also yielded no result. I then did a hard reboot. Once more, I entered the boot pa... Read more

Dear All,

My computer has been infected with a Boot.TidServ.B virus.

Norton Recovery Tool has detected it, but can't fix it. Is Norton Power Eraser likely to be able to kill this kind of virus? What other options are available? NB the computer can't boot up, including in Safe Mode, so any solution would have to be run from CD/DVD ROM.

I've done a bit of research and come across an application called "TDSSkiller" from Kaspersky - is this likely to work? Note that, again, it would have to be run-able from CDROM.

Thanks in advance for your help.

My hard drive will not boot without using a bootable CD to reference the Windows partition.

When I power on my computer, the BIOS POST displays, then a black screen with a blinking cursor (_) in the top left appears. Nothing happens after this, no error messages or anything.

Current Workaround
I can place Hiren's BootCD (Hiren's BootCD 15.1 - All in one Bootable CD ? www.hiren.info) into the drive, and allow the computer to boot to this CD. Once it is booted, I can scroll down to the menu option "Boot from Disc 0, Partition 2", and the Windows 7 install on my C:\ drive will boot like it should.

BackgroundThe drive originally shipped with Partition 1 as a 10gb recovery/restore partition, and Partition 2 is where Windows 7 was installed.
At some point, the recovery partition had data on it accidently deleted, rendering it useless.
Ubuntu was installed as dual-boot with Windows 7. This shrunk partition 2 (Windows 7), and added partition 3 (200gb) and partition 4 (50gb) for Ubuntu. It then booted to a GRUB bootloader which had Windows 7 as the last option on the list.
Uninstallation of Ubuntu. I used the methods shown at this link: The Non-Geek?s Guide To Safely Uninstall Ubuntu From A Dual-Booting MachinePartitions 1, 3, and 4 were deleted using EASUS Partition Manager in Windows.
Partition 2 (Windows 7) was moved to the beginning of the hard drive and enlarged to use the entire disc using Disk Management utility.

Hello everyone,

Problem: Win 7 64bit - "Preparing your desktop..." on boot everytime after successful chkdsk.

My laptop is Acer V3-571G (Amazon.com: Acer Aspire V3-571G-6407 15.6-Inch Laptop (Black): Computers & Accessories). HDD, no SSDs. No HW malfunctions or anything since bought ~1 year ago.

Can't access any .msc ("dependency or service started to fail...") (so I can't create/access an admin account or use system restore) or .exe files , the sound is gone (I didn't install any outdated sound drivers).

At first, "preparing your desktop" caused all my start button contents gone. Then I logged off, logged back in - they were there, only "recent files" missing. Rebooting 2nd time resulted in "prep..." but start button contents intact. Some progress lol?

I also cannot download any files from the internet. This later throws some "tdDB ..." error.

Frequent "system_path... refers to a location that is unavailable. It maybe somewhere on your HDD... blahblah.".

Tried 5 subsequent reboots. None of them corrected the desktop. Made it even worse (black + Windows classic default style), so I had to log off/on again.

I don't have a Win7 64bit repair CD close by and can't access system restore. What are the options then?
Any reliable solutions/software for a rebootable CD?

P.S. I looked in the inet how to launch cmd in admin mode and such. But even run as admin doesn't work.

A:"Preparing your desktop..." on boot everytime after successful chkdsk

ADDITIONAL NOTE: chkdsk has replaced 5-6 bad sectors on laptop's HDD. Maybe there was files in those sectors related to the "thorn apart" user profile on Win7? (It's not corrupted I think, as it does not tell me I was logged onto a temp. profile (before welcome screen).)

Please help!! This is extremely annoying.

I am having this really strange error with one of my computers.

My computer (running Windows XP Home) boots normally and I can use it just fine. When I leave it alone for a while though, I come back to a screen with the message "Hard Drive not found." If I reboot the computer it loads normally and I can use the computer like nothing ever happened. It has done this twice now. It doesn't happen while I am using the computer but if it sits for a while this will happen.

Any suggestions as to what this is?


A:"No Hard drive found" message after successful boot.

Could be an issue with it going into standby mode or the power saving feature where you can cut the power to the HD after a certain amount of time.

Try right click desktop -> properties -> screen saver -> power, and make sure turn off hard disks is set to never (these steps are for win 2000, but I think it works for XP too). You could also turn off standby mode and see if you get the same problems.

When i boot up my computer it doesnt reach the user login screen before it loads of startup repair. It looks for a fix but it doesnt find one. In the diagnosis the only error it shows is 'Boot critical file C:\Windows\system32\drivers\vmbus.sys is corrupt'. I have booted kaspersky repair disk and run a full scan which found no viruses or malware etc. From the startup repair window i have tried a system restore which had the same problem when attempting to boot. I can only access the system recovery options screen.

I am running windows 7 32bit, and i dont have a windows 7 disk but do have the windows 7 32bit iso file that i used to install windows 7.

I would be grateful for any help to resolve this issue.

About 3 days ago I reinstalled Windows 7 and though I would XP on this same HDD rather than my seperate one the installed Linux Mint. So I installed it in this order - Windows 7, XP and Linux Mint

Rather than using the Linux boot menu because it showed me Windows 7 twice rather than Windows 7 and XP So I used EasyBCD in Windows XP and added XP to find the drive its self and linux as well. Linux and windows 7 I can boot ok but when I choose the option for XP it just goes to a black screen no windows loading screen or anyhing just a black screen.

Does any have ides with this for me?

A:Triple boot unable to boot XP

My first view of this is that you failed to check the box in EasyBCD
Run EasyBCD.
NOTE: This is required to repair the Windows 7 boot file and add XP to the Windows Boot Manager list.

9. On the left side of EasyBCD, click on the Add New Entry button. (See screenshot below)A) In the top section under Operating Systems, click on the Windows tab. (See screenshot below)
​B) To the right of Type, select Windows NT/2k/XP/2k3 from the drop down menu. (See screenshot below)
WARNING: Be sure to leave the Automatically detect correct drive box checked.

C) To the right of Name, you can leave the default Microsoft Windows XP as the name to be displayed in the Windows Boot Manager, or you can type whatever name you would like to have instead. (See screenshot below)
​D) Click on the Add Entry button. (See screenshot below)

​10. On the left side of EasyBCD, click on the Bootloader Setup button, select (dot) the Install the Windows Vista/7 bootloader to the MBR option, and click on the Write MBR button. (See screenshot below)
​11. Close EasyBCD.

When I try to start my laptop the 'Acer' logo flashes with 'press f2 to enter setup, f12 to change boot device, then to a black screen with a flashing cursor but unable to type, then screen turns off and it just repeats over and over. I'm unable to start in safe mode. I don't have the original Windows disc and no access to another computer, at this stage. I have a wireless keyboard and when I plug in the dongle am able to use it. 
If I press f2 then I'm able to access 'Phoenix Securecore Tiano Setup' with tabs for Information, Main, Security, Boot and Exit.
Before the laptop refused to start it was having an error about not being able to write to drive. I ran two programs, one anti malware and the other I think was Glary. I was able to start both in normal and safe mode at this stage.
Anyone have any ideas how to fix this? Dumbed down advice would be great!
