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.)

Hey Guys,

So I just got my hands on Windows 7 and wanted to play around with it, and everything works but:

Previous Computer Setup:
I had a dual boot with XP and Vista that worked perfectly (both OS's were on separate HD's and worked / booted correctly.)

Drive C: --------> Vista (Now Windows 7)
Drive D: --------> Windows XP

After upgrading my Vista to Windows 7 (Via clean install) I lost my boot menu to choose XP. Now everytime I flip the power it boots DIRECTLY into Windows 7.

How do I recover my boot screen option so I can boot back into XP when I need to?

 Hello, I recently reinstalled by laptop due to a faulty install of windows 8 which made me unable to start my pc and it got stuck in a bootloop. The reinstall was succesfull. However, when starting up I have to pick an operating system which means that I have two installed versions of windows on my harddrive. The first one works, the second one doesnt and shows a winload.efi missing error. I've tried removing the second install but so far I have been unsuccesfull, does anyone have any tips on how to remove that install without removing the working one?  I have added a picture of the OS-picking screen and of my harddrive partitioning. Thanks

Hello, My T-480 came with Windows installed on the 128 GB Toshiba drive. I would like to reconfigure the system with Windows on the 512 GB Samsung drive and a Linux distro on the 128 GB Toshiba drive. What is the best way to achieve this goal without driver issues or Lenovo tools issues when reinstalling Windows please? I created a Windows Recovery disk and hoped I could trick it in doing a system reset on the Toshiba drive by manipulating the boot order in the BIOS but that made no difference. Any help would be greatly appreciated. George

I did a dual boot install of Win7 and XP on separate HDDs. Plugged in one drive installed XP with F6 AHCI drivers. Then plugged in 2nd drive and installed Win7, loaded AHCI drivers from USB flash. Everything went great, no need for any EasyMBR tool. I would turn on computer and get boot option for Win7 or Earlier Version.....and still had access to all restore points in Win7.

Reason for reinstall - I was having problems getting rid of everything related to Nero, wiped some things out of registry that I guess XP needed and it would not start all the way. I tried to run a repair on XP and it worked, but lost my boot option for Win7.
Fine, I thought I'll just reinstall both OS's again since it was so easy the 1st time. XP installed with no problem.
I booted up with the Win7 cd, chose the Custom/Advanced Option
High lighted the old partition and deleted it
Chose New from unallocated space and went with the recommended size of about 114442 MB (120GB SSD)
Clicked format and the blue wheel spun for 5 seconds and stopped (Problem 1)
Clicked load drivers and browsed to the USB flash card that has the AHCI drivers on it
Chose the same folder as the first time I did the dual boot without a hitch, got error message (problem 2)

Problem 1 - Why is it not formatting for more than 5 seconds, should take at least 45 minutes from what I remember?
Problem 2 - When trying to load AHCI drivers why am I getting the following message (No signed device drivers were found. Make sure that... Read more

A:Can't reinstall windows 7 on dual boot with XP

Why would you reinstall both OS"s after XP was repaired but you only lost the WIn7 boot? All you needed to do was install EasyBCD to XP to add WIn7 back to the Boot Menu? Or Mark Win7 Partition Active
then run Startup Repair - Run 3 Separate Times until Win7 starts and then add XP using EasyBCD. Takes 5 minutes.

You're attempting to apply XP methods to the Win7 install which no longer apply: Quick Format is all that's used during install, and there is no need to add storage drivers as they are all in the installer. In fact a prompt for drivers during 7 install almost always means a bad installer.

Last year I installed Ubuntu 9.04 on my Dell Dimension 5000 running Windows XP Pro, giving me a trouble-free dual boot system until recently.

Recently though, I've had problems with Windows being excruciatingly slow, some crashes, unexplained error messages etc - probably partly due to a load of unnecessary and now unwanted programs I've installed along the way. I would now like to start afresh with a clean reinstall of Windows - but am worried about possible complications with my Ubuntu installation and some horror stories I've heard about messing with the Master Boot Record. I do not wish to remove Ubuntu, and have had no problems with it.

Can I simply format my C drive and just install Windows again? Or am I rushing in where angels fear to tread? I have my Win XP Pro disk. I've reinstalled Windows in the past, but that was before I had installed Ubuntu.

I'd really appreciate some advice and a step by step guide on how I should proceed - thanks!

Not really, you should be able to just format the partition and Clean Install Windows 7

But we can advise you better if we see a screenshot of Disk Management - Post a Screen Capture Image.

In addition look over these steps for Clean Reinstall - Factory OEM Windows 7 which compile everything that works best to get and keep a perfect reinstall, even for retail.

I have Vista Home Premium 64 bit and I downloaded 64 Bit RC Windows 7 and did a clean install on another partition of my hard drive. Dual boot was working for about 4 days then all of a sudden it doesnt come up any more. The partition is still there with Windows 7 installed on it but its not booting under it. I go into MSConfig and Windows 7 isnt even being detected, checked the advanced system options in the control panel and it isnt there either.

Any idea how to recover windows 7? I did not install it from dvd, I installed from Daemon Tools and worked fine.

Do I need to Burn the image to a DVD and run it on startup if I want to run Windows 7?

Hello all, new here, my pc config is intel quad 6600, 4gb ram, 2 320gb hd, OS is XP Pro with SP2. Okay I heard people speek highly of Vista and no so highly so I decided to give it a shot and make my own decision.
XP was installed a few weeks ago and is on disk 1 50gig partition, created another 75 for E:Vista Ultimate and have 175 unallocated for now. My other drive is just for games.
At first I used the remaining 250 for Vista the first time. Everything loaded fine was online with Vista was updating drivers and then I rebooted to finish the install for some drivers and the boot options never came up it booted right to XP.
I looked at the partitions and it shows Vista there so I looked in XP boot.ini and it shows:

[boot loader]
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect /NoExecute=OptIn
I checked around and people said to add Vista to it so I did and added this:

[boot loader]
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect /NoExecute=OptIn
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Microsoft Windows Vista Ultimate" /fastdetect

I have lost the ability to dual boot after installing windows XP.

I Originally had windows XP. I partitioned the drive in order to install windows 7. Installed windows 7 fine, no problems, was able to dual boot. After getting data from XP partition. I decided to do a clean install of xp. After doing that my machine only boots into XP, I no longer have the dual boot option.
I have tried booting off the windows 7 dvd and 'repair computer'. It said it found some problems and fixed them. Rebooted, still only booted into XP. Tried booting off DVD again ran 'Startup Repair option' Again, said it fixed some things, still only boots into XP.

I also tried EasyBCD and it said it fixed the problems, but everything is still the same. I can only boot into windows xp. No dual boot.
My boot.ini, ntldr and ntdetect are all on partition that has windows 7 installed.
Saw the posts about Vistabootpro but wanted to make sure i went that route before i purchased it and wanted to make sure of the correct steps to follow.

Hello Greg,

Do you have Windows 8 set as the default OS to run at startup? If not, then you will see the boot screens that Windows 7 uses instead of the new Windows 8 ones.
You might see if you could use a different option to boot to the Startup Options Menu to get to the Advanced Boot Options screen.

Hi. I have win xp sp3 on my laptop.
I wanted to install dual boot with windows 7.
So i created a new partition of 20 GB (drive D).
THen i installed from win 7 dvd, and choose Drive D for the installation.
After all the install and config, the original drive C (xp) had no letter, and the drive D, now is Drive C. 20 GB with win 7 installed.
So i assigned a letter (E) but the drive is completly empty, 0 bytes 0 files.
Obviously i have no dual boot, since there is no xp partition.

Is there any way to get back the data in the XP partition ?

Are they all lost ? i dont understand what happened.

Ok let me make sure I know whats going on, you went to dual boot however the primary drive somehow got re-formatted correct? You still should have 2 partitions on your drive. You have already looked on your disk Management service correct? If not, that would be the first thing I would look at.

Or maybe you'll be lucky enough that when you plug in your drive as a secondary hard drive(using another computer) you MAY be able to see your xp partition and just copy the files directly. --Hope this helped at all

i have some questions regarding dual booting windows 7 home premium x64 with linux fedora 14 on dual independantly dedicated drives. i am a college student with moderate computer (windows) knowledge but am doing software development and would like to play around with some linux for a class. i have no prior experience with linux and have minimal knowledge of operation. i am currently running windows 7 and would like to keep it as my primary os. i do not wish to share media files across drives or os's, windows does that just fine as is and i dont want to get into a third drive. my current drive is a 1tb wd black caviar hdd. it is also currently 2/3rds full and the desktop is about 6 months old so i would rather not partition the drive for a dual boot. i would think that there are some other advantages for the os's operating independantly off their own drives other than if one hdd dies i should still have the other with its os still ok. i have read some topics about RAID configs with dual boot setups with dual drives like this but am not very familiar with RAID. is there a RAID config that would be beneficial in this situation? i currently do not have a RAID card. my tower internals are not very accessible and i dont like the idea of disconnecting drives depending on which os i want to operate. so what would be the best way of going about this? this is a near future project so i am looking for someone with some experience in this area hopefully.

I just installed a new 10k rpm drive on which I want to do a fresh xp pro install. My current os is on my C drive (80gb) along with other stuff I need (about 55gb). I didn't partition it in the beginning which I now regret. So how can I install the new os and keep the other C drive data. I don't know if I should attempt some kind of dual boot. Or is there a way to disable windows on the c drive after the install on the 10k?
I have no space to backup 55gb of data. My theory is that I can install xp fresh then reboot and be prompted in dos to choose which OS. it's a little confusing what I should do first.

I would greatly appreciate your insight.

Hey guys,

This is probably an easy solve but here is my situation:
Drive D: Windows XP Professional 64Bit
Drive F: Windows 7 Professional 64 Bit
Drive D shows as System and Active Drive
Drive F shows as Boot Drive
Drive G is Data
All drives are Primary and physical drives all drives are also NTFS when running Disk Manager
Dual Booting system

Here is what I need to do:
I want to uninstall or format Drive D and install Windows XP Professional 32bit so I can have an OS that runs my older games I have not played or played in a while.

A few Questions I have:
1. How can I tell what drive controls the Boot Block, is that the system active drive (D) or the Boot drive (F)
2. Can I make Drive F System and Active? (will that destroy the Master Boot Block)
3. Is the master boot block the same as what controls the Dual boot?
4. Is there any way to make Win7 my C drive and the new Winxp32bit my D drive like normal people...lol

Note: I think I got to this condition where I dont have a C drive by having my C drive go bad and I recreated my MBB to point to the Windows 7 disk.
Getting old, cant remember diddly. LOL

When you install Windows the boot will be set to boot to that Windows only (in your case; non-newer Windows installations could be included in general). So the outline of how to proceed is

a. decide how you will get back to the dual boot you want, and make preparations if needed.
b. install Windows.
c. restore the dual boot.

As I assume that you have a GPT disk and UEFI motherboard I cannot give any more details.

I'm thinking about reinstalling XP sometime, but I was also thinking about a Linux distro to install as well. I run a 6 month old laptop with a 40GB hard drive. I was thinking of either Red Hat or Mandrake. I was wondering if it was better to use the XP installer to partition my hard drive, then install XP first, or if it would be better to do Linux first. I'm curious about the advantages of either of those distros too. This is really my first time with Linux. Thank you.

I have 3 partitions - 1=Vista, 2=Win 7, 3=Data.

Dual boot had Vista as default but Win 7 available too.
The Win 7 installation started coming up with a Winload error and would not repair.

I Booted from Win 7 RC DVD, deleted partition 2 and re-installed Win 7 on the new, unallocated partition 2.

Now the system boots ONLY into Win 7 with no Vista option.
Advanced System Setting shows only Win 7. How can I add my Vista, partition 1, into the dual boot set up?
Vista is my "LIVE" system. Win 7 is for evaluation, learnning only.


A:Reinstall Win 7 has stopped dual boot

You could repair Vista to get that booting, using the DVD, and then do away with your dual boot setup. I despise them for many reaosns, but this being one of them. You're top priority is getting your production system back online, and then you can worry about testing Windows 7 later. By now, you probably know what you plan to do when it is released, so I wouldn't bother putting an RC back on there. If anything, get the RTM from Microsoft if you need to do more testing.

Hi guys,

I know I'm probably just doing something stupid, but I recently had to reinstall Windows 7 in my dual boot system. Windows 8.1 can no longer "see" Win 7 and won't dual boot with it. I tried EasyBCD and all it did was corrupt Win 8.1's Bootmgr to the point where I had to use Automatic Repair from the Win 8 install disk to get 8.1 to boot again.

Short of reinstalling Win 8, is there anything I can do from Win 7 that will re-enable dual boot? Or is there a way in Win 8? I tried a couple of the Win 8 tutorials, but the option for Win 7 never came up in the boot options screens.

Any ideas gratefully received.

I recently bought I new Seagate 500GB hard drive with plans to rebuild my PC from scratch as both the partition with Vista the other partition with XP was slowing down. The original hard drive was a Seagate 320GB that was partitioned for the two above OS's. After saving all my personal files on a portable hard drive, I booted up the computer with the Vista CD and reformatted the drive as my way of deleting everything and starting from scratch. After I did this, I connected the 500GB hard drive and began a journey of a lot of frustatrion and wasted time. Let me say it right here that it isn't a faulty new hard drive.

Now, a blue screen pops up at every bootup as soon as it starts to read the hard drives (and it doesn't matter what order I set them up to boot in BIOS).

Just today I needed to reinstall XP on the same partition that it was on. Now my problem is that because of the reinstall, the bootloader that Win7 changed is now gone and I no longer have the option to select Win 7 during bootup.

Is there away to get the option back without having to re-install Win7 all over again?

I am new here,
I was wondering if you can please help me with this issue.
I have basic skills.
Recently I created a dual boot system with win 7 and 10, on separate hard drives. Vertex 3 and Samsung 850.
I have created clones of each drive using acronis on separate hard drives, thinking if any problems I can re-clone the appropriate hard drive.
Yesterday I had a problem with win 10 and used the cloned image. Sadly, on boot up i get the blue screen saying press F8, F9 etc.
My question is how can I reload the win 10 cloned image and get standard options of either win 10 or win 7 at start up-like before.
I did not make a boot up disc-thinking there is no need.
I would be grateful if you point me towards a tutorial to resolve this please.
Many thanks-looking forward to some help.

If everything goes well I'll be building my first gaming desktop later this year.
One of the scenarios I'm considering is having 4 hard disks and two OSs,
a1, a2, b1, b2
the a disks would be 128 SSDs each with its copy of Win7,
the b disks would be 1 TB HDDs with data.

I want a1 (when I boot with it) to recognize only b1, the same with a2/b2.
In sum, I want one of the data disks not to be seen/accessed by the "other" OS.

Is this possible, and if yes how?

During install of each OS, unplug all other drives. Set preferred OS to boot first in BIOS setup, then trigger the other OS SSD using BIOS Boot Menu shortcut key.
If this isn't to your liking install EasyBCD to add the secondary OS to a Windows Boot Menu. This way the drives will still be independently bootable to come and go as you please. They would not if you leave the other one plugged in during install.

I have a dual boot installation with Windows XP and Windows 7 on the same drive with two partitions. Both work just fine.

However most times that I boot from a cold boot, I get NO Boot options menu, just a blank screen and the hard drive light glows red, but it doesn't really seem to be doing anything.

If I press the reset switch, everything works just fine, the computer reboots, I get a boot options menu for selecting the operating system and either one boots up just fine.

If I shutdown the machine for any period of time, I'll get the blank screen until I do a hard reset.

It seems like the boot loader is not finding the ini file with the options, but only on a cold boot? Any suggestions would be appreciated.

When in ME, can you insert the xp c.d. and get it to run, if so, you can repair the boot sector and get your 2 drives back.

I have an XP / 98 dual boot set up that has worked well for over a year. W98, the original operating system is set up on the primary partition and XP has it's own logical partition on the same drive.

XP continues to boot up withput problems, but with the W98 option, it stalls after the wallpaper loads and before any programs or system tray loads. It holds for about a minute and then automatically tries to re-boot.

I have tried to boot to Safe Mode, but 98 will still not start. I have tried System Restore in XP, but I can't get back to any restore point from previous days. No changes have been made to my system other than a game installation which failed and had to be uninstalled using the game program.

I suggest you download and install easyBCD and use it to find your other OS and repair your boot manager

Hey I've been reading the forum now and then so I decided I finally sign up and see if I could get some help. I'm not sure if this would be the correct section so I apologize in advance.

The problem I'm having is that I had been running WinXP SP3, I used GParted to partition my hdd so I could do a clean install and try out windows 7. The odd thing is though, at first when it would boot up I'd have two option to select from, either "Windows 7" or "Select an older version of windows", then I reinstalled windows 7 at one point(to the same partition used before) and lost that menu all together, now whenever I turn my PC on it just acts like windows 7 is the only OS installed. I know my other partition is still there though, my question is, how would I go about retrieving it if possible. Can I just pop in my WinXP disc and do a repair or recovery on the other partition? Never had this problem dual booting windows and linux so im unsure as to what I should do.

A:Dual boot lost?

win 7 rewrites the masterbootrecord, i guess to break SLI loaders. Best is to do a repair with your xp disk and rebuld the xp bootrecord.

As said in the topic, I can't start windows Vista, because I don't get up any boot options, the computer just boots into XP no matter what.
I have tried using easyBCD, followed http://neosmart.net/wiki/display/EBCD/Troubleshooting+Windows+XP troubleshooting, but everything seems right. Can anyone point me in the right direction? I have tried a lot of things, but none seem to work. I have a fresh install of XP, but old Vista.

In advance, thank you.

I had my hard drive broken into two partitions. XP and WIndows 7. Everything was fine with windows 7 but xp was acting odd so i decided to do a fresh install of XP on the XP partitition (since i had moved al data from xp to windows 7)

After doing the fresh install of XP i no longer have the option to dual boot. It just boots directly into XP. (I have no menu saying 'Earlier versions of windows or windows7).

The partition and al files are still there on the windows 7 partition.

The only boot.ini file i can find is on the windows 7 partition and it looks like this.

[boot loader]
[operating systems]
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect
so I can see that there is no windows 7 option, but am not sure what to do so i can get back to my original dual boot menu with the choices of 'Earlier version of windows' and 'Windows7'

I was thinking i should just run the windows 7 cd and run fixmbr but did not want to go that route till i found out for sure that it would fix the problem.

Thanks in advance for the help.

UPDATE: After some searching on the net i tried booting off the Windows 7 cd and selected the language and keyboard layout and clicked NEXT. Then i clicked the small link at the bottom to repair. It said it found an error and that it added windows 7 to the boot. Restarted. Still only booted into ... Read more

Ok, i have windows 7 already installed fine on my 2x raptor raided drives, i decided to install xp 32 on a new partition on the 2x raided raptors, after using nlite to integrate my raid drivers into the new xp iso (no floppy) it installed fine on the new partition.

However, i saw no boot menu on reboot and every time xp would load by default with f8 showing no other OS to boot. I then ran the windows 7 64 dvd and attempted a repair of startup option, it failed 5 times in a row quoting a corrupt boot sector.

I was all ready to give up when suddenly it just repaired it after the 6th attempt, i did nothing different but it said to reboot so i did and to my incredible relief my win 7 install started booting again.

But again, no boot menu and this time the xp boot has been lost! Is there any way i can manually add something to get a dual boot function running?

Download EasyBCD or VistaBootPro. You can add entries for any OS using its nice GUI.

I know I messed this up hopefuly someone can help
MSI Wind 210 Netbook, 250 gig hd, vista (came with it) then upgraded to win7 (2nd boot option)

I deleted the dual boot menu using partition doctor (dumb mistake, dont ask) now all that shows up when I goto boot is:

bootmgr is missing
press any key to restart

pressing a key...

intel undii, pxe-2.1 (build 082)
reboot and select proper boot device

thats it

It came with restore via the f3 key option on boot , but that shows nothing

Any suggestions on what to try?

Maybe this post is little bit off top, but anyway, help much needed!

My disks configuration is:
disk0, partitions: p1, p2
disk1, partitions: p3, p4.

I had dual-boot,
win xp from partition p1
win xp from partition p4

Yesterday something happened to partition p1. When I tried to boot from it I got blue screen and restart immediately, when I booted from p4, boot was slower than before, and I couldn't access disk on partition p1 (got disk not formatted error).

So using TestDisk I recovered files I needed (yes, using TestDisk partition seemed to be ok), then tried to recover partition, boot, mbr. TestDisk told me that everything was in perfect shape... but actually boot from p1 wasn't working, and I couldn't reach that drive when booted form p4.

So, I decided to recreate partition and reinstall win xp on p1. Reinstall went ok, but now I cannot dual boot. Is there any way to recover my dual-boot without reinstalling win on p4?

Waiting for any information,
Best regards,

Description: Hi. Bootmagic was installed with 2 primary partitions and two other partitions for data. Two operating systems were installed in the primaries: Windows 98SE chinese, and WIN2K english. Then, I installed XP in one of the 2 partitions without an operating system. Upon restarting, I no longer had bootmagic menu available, only xp multiboot menu to choose from XP and Win2k. The second primary partition [C2] with windows98se is still there but hidden. I want to have XP, Win2k and Windows98SE chinese again and be able to choose. Also, in the future I may want to try Linux. What should I do? Can I just delete the hidden partition and then create another and reinstall a system on it? Does XP perform the same multiboot functions as Partition Magic and can be used for this? I really don't want to have to start from scratch and reinstall everything, now XP and win2k work fine. Thanks

Also, can I resize the boot partitions and add the free space to my data partition?

I have a 250gb hdd that I've partitioned in half to accept both operating systems. I've done formatted and clean installed the XP and formatted the second partition to accept Vista. Install was clean on both. But as soon as I boot to Vista, I will lose my sound in XP. Device Manager says all is well (it's not) Latest driver is in. I can't get any sound at all from XP. I had a similar problem with RC2. I use an integrated sound card on an Intel D101GGC board. (Realtek). I am now bald from pulling my hair out trying to figure this one out. Any Ideas?

I've tried to deleting and reloading the driver with still no success.
