unable to boot os

Q: unable to boot os

OS Version: Microsoft Windows 7 Home Premium, Service Pack 1, 64 bit
Processor: Intel(R) Core(TM) i5-4460 CPU @ 3.20GHz, Intel64 Family 6 Model 60 Stepping 3
Processor Count: 4
RAM: 16245 Mb
Graphics Card: Standard VGA Graphics Adapter, 6 Mb
Hard Drives: C: 1863 GB (1827 GB Free); E: 287 GB (258 GB Free);
Motherboard: Gigabyte Technology Co., Ltd., Z97MX-Gaming 5
Antivirus: None

So for the first time in 15 years I have come across a problem I cannot resolve even after doing extensive research online. My pc was working fine when a couple days ago it started a boot loop and wouldn't boot the windows 7 os. I connected a hard drive from my laptop which was installed with the same os (E: in the details above), however none of my other hard drives will boot. When I boot from laptop hard drive I can see all other connected hard drives, can format, re-partition and reinstall windows to them, however if I disconnect it, once again I cannot get the windows os to boot. I have checked that the partition is active, boot sequence in BIOS, switched from legacy to uefi and back in BIOS, done bootrec repairs, switched power cables and SATA cables, all with no result.
If anyone has anything else I can try I would be most grateful.

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!

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!

Hi,
This morning I went to use my laptop and it is no longer booting.  The power will come on and the power button lights up, the keyboard lights up.  If I let it sit it will stop running after around 30 seconds to 1 minute.
If I click the power button after it started, I can hear the fans spin up then the system shut down.  I have ran the LCD test and it works.  Their is no boot screen at all or dell screen.
I updated the bios last week and I had run it since.  I also took the whole thing apart today to remove the bios battery for 1 minute and put it back together but it still does not run.
Is their a way to diagnose motherboard issues?  why would it not boot or is their more steps to look at?Thank you

Welcome,
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.

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.

Hello,

I own a HP Pavilion Tablet with Vista Business. I haven't noticed it until just recently that the CD-ROM drive disappeared off device manager. In an attempt to remedy the problem (hoping it was a software problem), I do what I usually do: rstrui. When recent restore dates didn't work, I turned the clock back the oldest state I had, which was back in late September. Next thing I knew, it wouldn't boot properly. It would pass the initial stage but would eventually end up on a blank screen. However, the cursor is visible (and movable). I can't progress through this point. BIOs is unreachable and it cannot boot from CD. I am unsure as to how to proceed from here. Any help would be appreciated, thank you.
 

A:Unable to Boot; Unable to detect CD

First and foremost, read your manual as to how to do a system recovery. There will be a key or key combo to hit when powering up like F11 or whatever. This starts the system recovery.

Note many of these will overwrite ALL data on the drive. If there is info you need ie work files, data files, etc; I would pull the drive and slave it to a working system. Copy whatever data you need. Reinstall the drive and do the recovery.

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

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.

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.

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

Symptom
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.

My first view of this is that you failed to check the box in EasyBCD
Run EasyBCD.

Hello:

Initially I had Windows 7 Ultimate (retail version) installed on my desktop. When I tried to install Ubuntu, I found that the hard-disk partitioning scheme was GPT. So I made a back-up of my drive's contents, re-partitioned the disk as MBR, re-installed Windows 7, and overwrote the disk contents with my backed up files.

This worked splendidly (i.e., I have all my installed applications, etc. intact) EXCEPT for one nagging issue: When I boot, if I let it boot directly into the hard disk, it does not work. I have to select F10 (BIOS boot options menu), and from there select the hard-disk, and only then Windows 7 boots properly.

I tried bcdedit, bootrec, etc. No use. Any recommendations, please?

Thanks!

A:Please help: Unable to boot normally

This will work for 7, also. First make a system image and put on a separate hard drive, just in case. Fixmbr can cause problems and you should have a back up

I restarted it and an error message in blue screen popped on the screen saying that Your PC/Device needs to be repaired "OS couldn't be loaded because the digital signature of a file can't be verified".

Hi all hopefully you guys can all help me with a little(major) proproblem im having with my desktop. Hopefully i give enough information (although im stumped myself)

My desktop computer is about 5-6 years old pentium 2 average specs. Yesterday it was working with out a hitch and shut down as normal after use. This morning I turn on the wal switch as normal but when i press the power button on the front of the computer, the red light turns on you can hear the fans etc going, the green light does not start nothing appears on screen, the computer for lack of a better word is dead.

Just the red light turned on, it doesn't blink and the computer doesn't sound like its processing anything, no boot up screen or anything.

I've checkd all connections and they seem to be fine.

Hopefully someone may have an answer to help me out.

Thanks for your time

I am working on an Inspiron 3721 and am trying to boot to the USB Thumbdrive in UEFI mode. .I have turned off Secure Boot, disabled Legacy, Boot List Option set to <UEFI>.  I have added USB as a Boot Option .  The File Path System is "Acpi(PNP0A03,0)/Pci(1D10)/Usb(0, 0)/Usb(1, 0)/HD(part1,Sig3DDE4903).  The File Path is "F:/Isolinux/"  and I have tried "F:/Isolinux/BOOT".

What am I doing wrong?  The Thumbdrive is a bootable drive.

I get this message on startup from my 64-bit vista pc:

"Windows failed to start..." and then the standard options (safe mode, start normally, etc)

No matter what option I choose, the next page is always the same.

"Windows failed to start...

If you do not have this disk, contact your system administrator or computer manufacturer for assistance.

File: \windows\suystem32\config\system

Status: 0xc0000014c

Info: windows failed to load because the system registry file is missing, or corrupt."

I have a manufacturers' recovery disk but the cd-drive isn't functioning.




How can I boot the recovery disk (or an .iso of it?) from a USB drive?

Hi, this is by far the best tutorial on this subject:-

How To Make and Use a Bootable WinPE Drive : USB Flash Drives

Once you get to the RE you will need to access the cmd prompt and :-

Enter the following commands to fix the issue.
We need to determine what OS the RE assigned a drive letter to (not always C) so at the x sources prompt type:- bcdedit |find ?osdevice? press enter (use the returned OS drive letter in the following cmds (assume C:).

(press enter after each command)
C:
cd windows\system32\config
C:\windows\system32\config>ren default default.old
C:\windows\system32\config>ren sam sam.old
C:\windows\system32\config>ren security security.old
C:\windows\system32\config>ren software software.old

My computer recently crashed and upon reboot it kept getting stuck at one of the startup screens. When i try to boot in safe mode it just hangs on loading the driver files, and now im having problems trying to boot from my windows cd. I set up in my bios to boot from cd first but it skips that process and still tries to boot from the hd. when i disable booting from hd as an option it keeps stating to restart the computer and boot from a proper source. Ive ran out of ideas here...any suggestions guys?

Hello Default08

It should boot from the CD if you set the order properly in the BIOS.
Try the CD in another machine to test if it is faulty.

The computer is a IBM T-40 laptop, 2G ram, DVD drive which was running XP-Pro (SP2) until I tried to install Ubuntu 9.1. The install from the CD seemed to go without problem but I am now unable to boot either OS. I tried the XP CD 'R' option and it reports 'path or file specified not valid'. My Win98 CD won't boot at all either (I thought maybe 'fixmbr' etc. might run from there). Using Ultimate Boot CD, Dr Dos 2 and also Gparts, the disk appears intact, with a 20G NTSF half filled (listed 'boot') and a extended partition with 3 Linux partitions, 2 with contents, one swap, but no 'repair' features from the'rescue CDs' help. I'm unsure if the machine just can't find the HD, the MBR or if the MBR is corrupt. I've tried every XP 'fix' I can find to no avail. Perhaps the Linux forum might be able to say if it can be fixed from there with 'Terminal' run from the installation CD. I can provide any additional details if there are any suggestions. Do I need to start over or can the MBR be repaired/replaced externally. Any direction appreciated. Thanks, AC

Dell Inspiron desktop w/ Pentium 1, several years old.Turned on in morning, computer starts POST but fails to complete, screen turn black, power still on, I can hear the HDD tapping away. Unplugged, powered back on pressed F8, F11, F2, or F12 to boot in safe mode or to do anything else but those screens come up on the monitor but go black after maybe one half second. If I'm lucky I can maneuver the cursor to Safe Mode then Enter before the screen goes blank again. But as its loading the Windows files (usually pages) the screen goes black again without completing the task. All the other screens do the same thing. Also I've held in the power button until it turned itself off and repowered again and the the screen showed the Launch Recovery option as expected but the screen goes black even if i'm fast enough to select it.I had a System Recovery CD that I had made a long while back that I assumed was functional but the computer wouldn't boot up with it in the dvd drive. All I got was cursor on a black screen OR nothing at all.Finally I was able to get into Safe Mode, not by doing anything different but just by repetively trying to reboot, finally it said Launch Recovery which worked. I did a ESET NOD 32 virus scan that showed a couple of threats that were deleted. I made a System repair disk, I went back to a previous restore point a couple weeks back when everything worked well. The computer seemed to work normally so I did a normal shut down and went to bed.... Read more

I made a mistake of re-partioning the 2nd HD ( 1 of 2 40Gb drives) this somehow corrupted the boot sector of the other drive with XP installed, I cannot boot the XP from the CD-rom drive the disk is not recognised as a system disk.

So I installed a new WD 160GB drive but still the same problem the message says non system disk and I have also tried soem diagnostic disks like the the one from WD.

The bios is correctly identifying both the new 160Gb HD and also the CD-ROm which is an Imation, which is now about 4-5 years old.

Everything was working before I screwed up, except I cannot be certain about the CD-rom, could it be this is not working properly.

I have a floppy drive but no boot disk and no way of making one.

Please anyone can you advise what to do.

Long story short my computer cant boot from a bootable usb.

Long story long, Yesterday i tried to format my computer with my windows 7 original disk, my computer does not have a slot for a cd player so i plugged one in and it was just laying there on the ground, i put my windows disk in and it was vibrating like crazy so i wanted to move it on a pillow, while doing so i tilted it a bit at it and it completely ruined the cd, i cant boot from it anymore so i lend a bootable usb with windows 7 on it, and put my bios priorites to boot from the usb and it gives me a screen with lines going down in different colors ( Blue, green, light blue, red) With Weird compination of letters ( C ? L O( @ C, ) and so on. Like the same effect of a blue screen, i cant press anything and only thing i can do is turn it off and on. What causes this? Its not just this usb its also if my computer boots from my extern harddisk ( Without windows7 files on it just picutres) So im guessing the usb isnt bootable? Or is there a setting im missing in the bios.

Thx for reading my rambeling

Setup:

intel i7 3930k
gigabyte x79 ud3
gtx 680
