Lost Dual Boot With Vista After Win7 Install

Jun 3, 2009

I just installed windows 7 ultimate on my pc.

i already had xp32 and vista 64 business on a dual boot on the same HDD before installing windows 7.

during windows 7 install, I selected the xp32 partition, formatted it and installed windows 7 over the top as I no longer wanted xp32.

When the windows 7 install was complete I expected to see a dual boot screen with

option 1. windows 7

and option 2. vista64

unfortunatelty i have no dual boot options, the pc now just goes straight into windows 7. It doesnt sem to know that vista is there.

i would appreciate assistance in getting a dual boot set up with vista64 and windows 7

Custom Install Win7 On XP Pro/Vista XP Dual Boot

Nov 3, 2009

I have just discovered that I cannot do an Upgrade from Vista HP to Win 7 Pro and that I will have to do a Custom or clean install. That will be OK and doesn't cause any problems.

I have XP on one HDD and Vista on another with dual boot. However I want to replace Vista HP with Win 7 Pro 32 bit, ( I intend to go 64 bit later on).

What I would like to know is, will Win 7 replace Vista on the boot sequence (MBR?), so that on booting the PC I have the option of selecting either XP or Win 7, or will I be presented with a boot menu of XP, Vista and Windows 7, albeit that Vista is no longer installed? If the latter, will this cause any problems in selecting the OS that I want to launch i.e the MBR looking for a now non existing Vista and would there be a way to remove reference to Vista?

Dual Boot Vista 64 / Win7 64

Aug 17, 2009

I've been going at this all day searching, trial and error, and it's all very frustrating at this point.

I use a custom bootloader for my vista 64 to trick it to be activated (not sure your policy on discussing this). But now I wanted to try Windows 7 since it has been released in the RC status (because I had aquaintances try 7000 beta, and no one liked it). So I want to have it on my machine to tinker with and test it out.

I ended up taking my 300GB drive, and removing about 60GB from it, creating a logical partition, formatting it, then booted into the Windows 7 dvd I have. (win 7 - 7600)

Firstly, it takes about a couple minutes just to load the files. Then once it finally gets to the splash* screen and the cursor appears.....it takes about 5-10minutes for the "install" window to appear which seems VERY odd since my machine is VERY fast.

It takes quite a bit of time to accomplish installing from loading to finished (30minutes maybe), and by then it overwrites my bootloader for my VISTA installation (so its not activated anymore), and it shows WIN 7, and below that Vista 64. Read more at the forum...

Vista Win7 Dual Boot

Jul 29, 2009

I started out with Vista 32 Ultimate installed on my machine. I created a second partition on that system drive , and left my data drive alone and installed Win 7 64 Ultimate RC on the new partition. The system boots to win7 with no boot menu to pick vista from, any ideas?

Updating Vista/Win7 Dual Boot With Clean

Aug 7, 2009

I have my current system with Vista x64 on the C drive dual-booting with Windows 7 RC installed on the F drive.

Is there a way to install the Windows 7 RTM to my C drive without destroying my Win 7 RC version? I want to leave it there until I have everything installed and working. Then I can format the F drive and start clean.

Or would it be better to just add the new Dual-boot to C drive and then remove the old Vista?

Dual Boot - Vista 64 / Win7 64 - Winload.exe Error

Aug 19, 2009

I have 3 hdd's.

1 x 160GB (SATA)
- Partition: ~149GB - Win Vista64

1 x 300GB (SATA)
- Partition: ~220GB - MISC
- Partition: ~58.5GB - Windows 7 64

1x 1TB (SATA)
- Partition: ~931GB - Games


I ended up taking my 300GB drive, created a logical partition, then booted into the Windows 7 dvd I have. (win 7 - 7100?, straight off ms)

Firstly, it takes about a couple minutes just to load the files. Then once it finally gets to the splash* screen and the cursor appears.....it takes about 5-10minutes for the "install" window to appear which seems VERY odd since my machine is VERY fast. It takes quite a bit of time to accomplish installing from loading to finished (40minutes maybe)...

After everything installs when I go to choose the Windows 7 option on the boot menu, I get this black SOD
Windowssystem32winloader.exe error 0xc000000D
Something about the file being missing or corrupt.

I took my Windows 7 disk, and entered command prompt through recovery tools (which takes at least 5 minutes due to loading time to get to each time).
I ran DISKPART, then did LIST VOL, so it would tell me the partitions and letters.
Then I took another window, and entered bcdedit. The letters matched up with the partition letters and the file DOES exist.

I've tried 3 different sources on 3 different DVD's to see if perhaps I had a bad image (1 x microsoft/2 x torrent), but that's not the case.
I've tried setting the path's again through bcdedit to make sure there was no data corruption in the settings, and that was not successful either...

So when I need to figure is out why it tells me the file "winloader.exe" is missing or corrupt, when in fact it is pointing to the right harddrive, on the right partition, on the right location.

Yes, they all show up on the BIOS post, yes it recognizes the 300GB drive in the setup without extra drivers. The only hdd it needs extra drivers for to see is my 1TB, but I'm not using that for the Windows 7 installation.

WIN7 / Vista Home Premium Dual Boot - TRASHING ONE

Oct 20, 2009

I have C Drive 250gb - Vista HP SP2 and, PARTIONED, also a W Drive 250gb - Windows 7 RC7100

Boot Manager list Windows 7 first, which is what I wanted and set via msconfig.

I think I am going to trash my Vista and install a clean Windows 7 on C drive.

I am thinking to do this:

1. From within Windows 7, go to msconfig and reset boot sequence to C Drive

2. Reboot. From within Vista, go to Disk Management and delete the W partition (and therefore Windows 7) and then to resize my C drive to full amount of C/W size (500GB)

3. From within Vista, load in Windows 7 DVD, go to My computer and set off setup.exe & do a clean install...or do I have to change boot sequence thru bios first and reboot to the DVD drive to do this?

I have all discs/drivers for my other applications and they are all working fine on my present Windows 7 drive

Or would I simply do an in-place upgrade?

I know I have to either purchase a new copy or an upgrade copy of Windows 7.

Is my thought process above correct?

Lost Win 7 Dual Boot After XP Install

Sep 15, 2009

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.

No Dual Boot Manager / Option Screen After Win7 Install

Jun 9, 2009

I've installed 64bit win 7 on a 2nd partion of my main drive running vista 64bit. The installation all went smoothly and loaded into win 7.

But when restarted I did't get a windows boot manager screen so i could pick if I wish to load Vista or Windows 7, instead my system just loads straight into Vista.

Do I have to enable my system to be able to see the Windows 7 install?

Upgrade Install On Win 7/Vista Dual Boot

Aug 25, 2009

Well i am currently running Vista Home Premium sp2 and Windows 7 Ultimate (build 7100) in a dual boot config for about 2-3months and loving it. I was wondering if i could upgrade my Windows 7 install to RTM without affecting my Vista install? Do you get a choice which OS you want to upgrade or does it go by what OS you load the upgrade disc from?

I would like to overwrite the Vista32 install with Windows7.

Anything I should be aware of?

I hestitate for example to set the Bios to boot from DVD while installing Windows 7 or will the Windows 7 install when rebooting during installation automatically default to the Vista32 partition?

Dual Booting WIN7 And Vista Home Premium

May 24, 2009

I posted here earlier (a couple weeks ago) about a painless installation of Windows 7 on a resized C Drive, which I partitioned into into a C Drive (Vista) and W Drive (Win 7).

All was fine until yesterday - I had been able to login into and out of both operating systems without drama - when out of the blue, for no apparent reason, whenever I try and log onto the Vista operating system, it allows me to logon as Rod with my correct password, but after the logon screen I get the "Preparing your Desktop" and and am presented with a Desktop and icons - but not for me! I get a bubble pop up out of the System Tray that says "Windows had trouble loading your Profile and has loaded up a temporary profile. Contact your administrator".

That would be me! I for the life of me don't know what happened. I have created no new users, nor amended any existing ones. Though, when using Windows 7 earlier in the day, I had to give access rights and permissions to All authenticated Users in order to access and use files on a separate (D) Drive.

Will this have screwed up my User Profile and login to Vista? How?

How Do I Keep Win7, Dump XP From Dual Drive, Dual Boot ?

Nov 12, 2009

As currently configured, XP is on drive C:, Win 7 was added to drive E:, and the system is currently run as a dual boot. Attempting to boot without the XP drive present will yield a "NTLDR is missing" error very early in the boot process.

I have already tried the following:

(1) I moved the hidden Windows Boot Manager files (bootmgr as well as the associated Boot folder) from the XP drive root to the Win 7 drive root.

(2) After physically removing the XP drive, I rebooted to the Win 7 installation DVD, and used the "Repair Your Computer" option to pull up the "Recovery Tools". Then, using the command prompt utility, ...

(3) I attempted to write a new boot sector to the Windows 7 disk using the command: Bootrec /fixboot, - that yields an error though. The Bootrec /fixmbr claimed success, but ultimately did not make Win 7 drive bootable.

I had to reconnect drive C: just to boot into Win 7 again to write this. I do have files backed up, but to format and reinstall files would take many hours beyond just the time to transfer 400 GB of data, since I have dozens of purchased applications that need to be freshly reinstalled and validated as well. Basically I want my E: drive now to be my boot drive while the C: drive is reformatted and used for general storage.

Any idea how to make my Win 7 drive bootable? Do I need a partition program that is more adept at creating a viable boot sector, or is that even the problem?

My system dual boots to either Windows 7 or Vista Ultimate, or, at least it is supposed to. Something happened and now the system just boots to Winodows 7 without giving me the choice to boot to either. When I use F6 I find that only Windows 7 is listed in the Operating Systems box.

Windows 7 & Vista Dual Boot Installation - Vista Won't Load?

Sep 13, 2010

New laptop has Windows 7 Home Premium 64bit. I have two business programs that won't run on a 64bit system. Partitioned the hard drive to install Vista Home Premium 32bit to create a dual boot system solely to run these two programs.Can't get Vista to load. Followed tutorial meticulously. All goes fine until the "Vista will boot for the first time" step. After this first boot, the screen returns to the "completing installation" page. However, the process dies here and the progress bar across the bottom of the screen never moves, even after an hour. Reformatted the partition and started over with same results. Multiple attempts always die after the first boot.

Removing Vista From Dual Boot Of Windows 7 And Vista?

Apr 5, 2011

I had recently installed windows 7 on my laptop running windows vista. I did not remove the existing windows vista installation, and thus win 7 was installed in a dual boot combination. Now, i want to remove vista from my laptop and use windows 7 only.The problem is that during installation, win 7 was installed on logical drive and windows vista was on the primary drive. Thus, i cannot delete/format the windows vista partition. Also I cannot transfer the boot drive to the partition containing win 7 because the vista partition is the active one.

Boot Menu Doesn't Show Up - XP And Win7 Dual Boot

Oct 30, 2009

I have XP (x86) installed on one partition.

Last night I installed Windows 7 (x64) on a separate partition.

Anytime I had tried this in the past, using Vista, it always detected the Windows XP partition, and gave me a boot menu with "Earlier Version of Windows" option to boot to.

This is not so with Windows 7.

How can I get the boot menu to show both options, to boot to XP or to Windows 7?

Triple Boot XP, Vista, And Win7

May 10, 2009

I have four SATA II drives, four gig memory, etc, in my machine that have Windows XP and Vista dual-booting. Both OS's are installed on the same physical drives; about 150 gig each partition.

I've freed up one of the drives, changed the BIOS to boot from the DVD, and installed Windows 7, 64-bit. The installation completed without a hitch and the setup detected everything, sans the Viewsonic monitor. Windows did have a driver for the monitor, but I used the one for Vista 64-bit from Viewsonic and we are good.

After rebooting Windows 7, I expected to have couple of boot option but there's none. No XP and/or Vista, just Windows 7. I've tried to locate the bootmanager in Windows 7, but I couldn't find it and that worried me. There was no backup made since it should've picked up the other OS's.

I didn't touch any of the bootsectors, nor did Windows 7; the latter one did make the drive a primary disk and installed the boot record there. After modifying the BIOS, making the the XP/Vista drive the first drive to be booted, XP and Vista came back, but Windows 7 disappeared. I can boot either OS's by changing the order the drives are booted by the BIOS, but I rather have the choice for XP/Vista/7 in the boot menu.

I am not sure why Windows 7 didn't pick up on the other OS's; the reason could be the SATA drives, if I'd have to guess. Since "disk 1" was set as the first drive to boot by the BIOS, Windows 7 did not check other drives and declared itself the only OS.

The question is, how do I add Windows 7 to the Vista's boot menu, or alternatively, how do I add XP/Vista to 7's boot menu?

Dual Boot Win7 And XP

Nov 10, 2009

I have a new PC with Windows 7 pre-installed. My old PC died, but I have the hard drive that has WinXP loaded on it.

The old drive has two partitions, one for data and one for the WinXP OS. The OLD drive WinXP OS partition is identified as G-drive under Windows 7. NTLDR is located in the OLD drive now identified as the F-drive partition under Windows 7.

I've used EasyBCD to add the old drive and have the drive set as F for the WinXP boot loader. When I start the PC, I have the choice of Windows 7 or WinXP, but when I select WinXP, the system hangs and won't let me proceed. I can only boot under Windows 7.

I've obviously made an error somewhere....thoughts/suggestions?

Dual Boot Win7 And Win 7

Dec 3, 2009

I want to set up a dual boot system with 2 times Win 7. One system with Office software and related, the other with multimedia software like Photoshop etc. My experience with Xp systems is that that postpones the unavoidable clutter that Windows creates on a system disk. Also, I found it convenient to be able to access the system disk of the respective one system from the other one that is booted at the moment (backup, repair,...).

Now I want to do that for my new PC, too. I have a new PC with one 250GB HDD for the two OSs, and two 250GB HDDs (RAID0) for data. How do I go about installing the two OSs on two partitions? My first tries showed that I need one 100MB partition for the boot manager; two partitions of 80GB each are for the two Windows 7 systems, and the remaining partition for the application software (paging file will be on the RAID HDD).

Dual Boot From Within Win7 - XP

Mar 10, 2009

I am currently the Operations Lead for a BF2 Modification called Project Reality, which is quite a popular game, but am having a few problems at the moment.

I installed Windows 7 - build 7000 when it first came out, as a dual boot, I liked it so much I carried out a full install and removed XP.

Everything worked fine up until a week ago, where I can now longer launch the game I develop ....lol, as it runs of the BF2 exe that means it is reliant when in multiplayer mode on Punkbuster, from evenbalance.com (an anti cheat programme).

This occurred I think when I carried out a Windows 7 Update. Looking into it I now know that Windows 7 and Punbuster are not compatible, and the statement from evenbalance.com, is that they will not support a Beta OS, which is fine I understand.

Therefore I decided to create a partition in Windows 7, assign it a drive letter, and then reboot it to install XP on that new drive.

All goes fine until XP does it initial reboot to continue its install, and it comes up with

"Disk error press ctl / alt / del to restart" ............. and thats it - nothing from then on in.

I had to use the Windows 7 DVD to "repair" the OS and then get it back on.

So for some reason I can not create a dual boot from within this OS.

Can anyone advise if I am doing something wrong here, or if mentioned before pass me a link on ?
