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.

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

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.

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?

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
Problem:
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?

When my computer wouldn't turn on in the morning I did the usual diagnostics; unplug things one at time test with spare components etc... Any way I qucikly figured out the PSU was dead so I ordered a new one and was back up and running. However when I reassembled the computer after unplugging everything (and removing the m/b) I plugged the HDDs back into different SATA ports from which they orginally came. When I came to boot the computer up I got the error message: 'BOOTMGR missing' or it may have been 'NTLDR missing' I can't remember.
I fixed this problem by using the 7 startup repair utility. I have no problem booting into Windows 7, but I have lost the option to boot into my XP install on anther disk. I looked in the boot tab under System Configuration and the only OS showing is this Windows 7 install. So my question is this: how can I get the choice of which OS to boot back?
(I should mention that the XP install is on a different disk from the 7 install).

I had Windows 7 and Xubuntu set up in dual boot by EasyBCD, a well known utility.Today the linux kernel has been updated and, after the following reboot, the choice of Xubuntu OS at the dual boot prompt didn't work.So I went through Windows, launched EasyBCD to fix things and:
- changed the order the entries (Win 7 up, first)
- selected Windows 7 as default OS
- removed Xubuntu entry
- added again Xubuntu entry through EasyBCD procedure
- saved (maybe I should have saved after each of the changes)
When I rebooted I've found that two identical Xubuntu entries, each pointing to the Linux OS, and no Win 7.I've tried to access Win 7 by Grub, but it points to the dual boot screen, so I'm at start point again.I don't have the Win 7 disk but the usual recovery partition. No backup. Going through the recovery partition gets me back to the dual boot screen..Is there any way to put it in order again? Could you suggestions work in this case?I know that, from Linux, I can install and overwrite MBR with free mbr.bin
sudo apt-get install syslinux
sudo dd if=/usr/lib/syslinux/mbr.bin of=/dev/sda
But I'm not sure it will give me back Windows 7.

I have messed up my dual boot of XP Pro and Seven
Seven was working well, but XP was playing up.
I did a restore from an earlier acronis image of XP.
XP now works again, but as you have guessed I have lost the dual boot menu to select Windows 7 when I bootup.
I know boot.ini does not apply with Seven.
Please tell me how to get my neatly tweaked Seven back on the boot menu,

I lost access to my windows 7 drive (Dual-boot windows 7 & Ubuntu). every time I try to run Windows 7 I get the message: Bootmgr is compressed, Press CTRL_ALT-DEL to restart. I could run Bootrec /fixmbr or diskpart or attrib to rebuild my mbr table through DOS command window using my windows 7 recovery CD. The problem I cannot access drive C: where my windows 7 are. I get the error message: Cannot open volume for direct access or system cannot find the drive path or specified. I still can access all my windows folders and files through home folder in Ubuntu. I don't want to reformat and reinstall windows. Is there is a way to run the DOS commands within Ubuntu

I have Windows 7 installed in C , Now I want to install XP in other partition (D) in the same HD, to work on dual boot.
I ask help from you because I could not do the installation by the obvious method: installing XP by booting its installation CD and choosing the D partition for the system, my Windows 7 stopped to work, I had to repair it with Windows 7 installation CD.

So, i've been using Windows 7 for a few months, and i decided to install XP on another HDD, which is completely empty. It all went well, except fot the dualboot thing, cause i can only boot XP. I've tried changing the boot sequence, and still only XP boots.
What can i do to make Windows 7 boot again?

With this setup, W7 booted every time, with no dual boot menu appearing. If I pressed F12 during startup, I got to a boot menu where I could choose to boot either W7 or XP, with W7 being highlighted. However, this is how I want it to look like:At startup, the boot menu appears every time, with XP highlighted, and W7 as an alternative.

After installing Win 7 ULT 32 and 64 several times
- I am able to install either 32 or 64 version as a first OS, but when trying to install it as a second OS on the SEPARATE PARTITION OF THE SAME SATA3 HD, it fails once the install starts at app 30 min to complete the install. Tried it several times and it always fails.
- XP Pro fails to install as either first or second OS (can not install it at all). It gives me blue screen.
When working with one OS only (either Win 7 32 or 64 ULT) all drivers install with no issues and system is stable so I assume my issues are not hardware related.
Here is hardware config:
- AMD 6 core 1920T
- SATA3 WD 1TB hard drive - Western Digitac Caviar Black WD1002FAEX 1TB 7200
- Sapphire HD 5770 Varor X video card
- 2x4GB of Kingston RAM
-Asus M4A89GTD Pro USB3 motherboard
-CoolMaster UAF920 case with 750W power supply (750GTX)

I'm really having fits trying to dual boot a friends computer with xp home SP3 after windows 7 pro 64 bit. I slipstreamed all the drivers for his board (asus P8Z77 V LK) into the disc and xp disc gets to the point of choosing the partition to install on. The partition created using windows 7 does not show up. Just shows C disk (corsair nuetron ssd) as one partition having the entire space. None of the commands to create or delete the partition work. Booting back into 7 and going to disk manager shows the disk to be correct : 100 MB system reserved, then the partition for windows 7 as "C", then the 20GB partition XP as "D". I have read that windows XP needs the partition to be "active" in order to install but don't know if this is true. At this time the "D" partition is not active, the "C" partition is. Tried to do this with all other drives (two 1TB western digital HDD) disconnected but that didn't work either.

I'm wanting to install Windows 7 as a dual boot alongside my existing XP set up and have been trying to follow the excellent guide at Dual Boot Installation with Windows 7 and XP
But I'm stuck at resizing the existing partition as described at Partition or Volume - Shrink
I get as far as the command prompt and selecting the drive, but as soon as I type "shrink querymax" or "shrink desired=15360" or even just "shrink" I get the message
"Diskpart has encountered an error: This service cannot be started in safe mode"
Now I can't see any way of getting a command prompt WITHOUT starting in safe mode.

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 have on my desktop a dual boot Vista64 and Vista32.
BCD is via Vistabootpro.
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?

I currently have Vista Ultimate x64 and Windows 7 RC1 x64 running in a dual boot setup. Each OS is installed on a separate disk drive. If I preorder Windows 7 Professional upgrade ($99) will I be able to do a clean install on a partition of my choice or will it force me to clean install over my existing Vista Ultimate partition ?? I understand that I cant do an upgrade in place from Vista Ultimate to Windows 7 Professional. My question is will the preorder Windows 7 upgrade force to me "kill" my Vista Ultimate partition ?

I have a Windows 7 installation (x64). I wanted to install windows xp 32 in a dual boot scenario for some backwards compatibility hardware issues (video stuff).Anyway, I read the various tutorials and I have used nlite to put sata drivers into my win xp install iso/cd.My problem is that windows xp won't I get the hard drive error message DURING the install (ie, the first time xp asks you to reboot, but long before it tries its various installation things) have tried the various things associated with this, Easybsd, a Windows 7 restore and using fixmbr/etc. I can get BACK into windows 7, but setting up the menu is pointless because xp never installs correctly to begin with. It seems that the guides on fixing this error message are assuming you get it after xp completes its install and tries to boot -- instead, I am getting the error DURING the install. I get a /windows directory on my partition, but it clearly isn't a complete install because I never see the windows install screens with the pictures, estimated time, etc.

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?

I already have windows 7 Ulitmate x86 but 1 day I came up with an idea of giving a try on x64 one by dual booting.. So I downloaded it legally from microsoft and I did every procedures required for the install. Shrunk my C drive and installed the OS on the unallocated free space on the drive and it went on perfectly. But the problem is the System Reserved partition showed up on the x86 OS. every time i open My Computer i can see the system reserved partition.
I could accidentally do something wrong with the partition if it remains unhidden so I want to hide it. I was thinking of changing the drive letter but I afraid that's going to give me boot problem. In disk management the System Reserved is labelled Z and marked as active. I tried to set my other partition as active that day but the pc cannot boot at all not even the boot manager showed up. However I managed to fix it using my recovery disc to access the cmd and reactivate the Z drive using diskpart.

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?

I'm going to make a clean install of windows 7 and therefor have some question
1)As I want to make a dual boot install with a Linux distribution I thinking about the Partitioning. I want to make following Partitions: [code] Windows 7 also always creates this small 100MB system restore partition. So what would be the best way to prepare these Partions. I would use GParted Live CD to create the Partition in advance, that everything is the way I like it. But I'm not sure if this works without problems for the 100 MB system restore partition (lasts time I got 2 100 MB partitions)
2) I want to move the Users data to a separate partition and found this guides: User Profiles - Create and Move During Windows 7 Installation [2]=User%20Accounts User Folders - Change Default Location(Don't know which one I chose to do so till now) But I see in Windows 7 there are much more useless directories in the users home directory:I've already learned the new Library system, but I still want to use the Users directory. But there is a great mess. Is there a useful/possible way to prevent the directory to mess up with all the sub directories, often created by some apps, don't really using the directory. Or are you just ignore the users home directory? Usually I got about 5 to 8 sub-directories in each Directory for a tidy system to find everything and have a good ordered system.
