Windows 7: Dual Boot Installation with Windows 7 and XP

20 May 2012   #1770

Mark Win7 partition Active before running Startup Repair - Run 3 Separate Times until Win7 starts and holds the System Active flags.

Then install EasyBCD to Win7 to add XP, accept offered boot files, autocompletes, Save, reboot to Menu.

Download your wireless driver from the Acer Support Downloads webpage for your model to CD/flash stick, unzip and install it to get online to update Win7 including the latest drivers in optional Windows Updates. Absent XP drivers you may to search to find an XP driver for the wireless device if the oldest one on Acer webpage doesn't work in XP, even installed in Compatibility Mode

Windows 7 64 bit

Hey just thought I'd report back on this, I bought XP pro with SP3 just tried to install it today and it's a no go. When it first restarts it doesn't go to the config screen it idles in the boot screen (press any key to boot from CD screen).

Looks like it won't install for me at all.

Edit: Wiped my computer and installed XP first then Win 7. Issues with BCD though, the duel boot screen doesn't show up, in fact the boot manager doesn't even work at all so I've had to run a repair from disc for win 7 meaning I can't access the XP partition at all now.

So others know: You didn't need to buy XP SP3 if you already own the OS, only find the CD with SP3 for your version available on the web.

Install EasyBCD to Win7 to add XP on the Add OS Entry tab: Accept offered boot files, let it autocomplete, Save, reboot. EasyBCD (free Download at bottom of page - no name or email required)

Let us know if this works. If not post back a screenshot of your maximized Win7 Drive map with listings, using Snipping Tool in Start Menu.

Help needed with dual Windows boot instilation

I am having a problem getting a dual boot instillation working. I have read all the tutorials and serched for a solution with no success.

Briefly, I have a computer (self assembled) with Windows XP that I use for image processing and want to upgrage to a 64 bit system. I bought Windows 7 pro and installed it without difficulty on a new 1 TB drive; nothing else is on that drive. Windows XP resides on its own drive. I can access either operating system with no difficulty by going through the BIOS and changing the boot order of the HD.
I installed Easy BCD on the drive with Windows 7 as suggested by many and get both Windows 7 and Windows XP as choices when I start the computer and the drive with Windows 7 is first in the BIOS boot order.
Selecting Windows 7 will start Windows 7 . Selecting Windows XP gives the error message:

Invalid Boot.inf file
Booting from C:\windows

I have replaced NTDETECT with no effect. I realize this is some sort of boot configuration problem but have been unable to fix it or find a solution after several weeks .

Any help would be greatly appreciated

Did you have the problem before adding XP with EasyBCD? If not, try removing it using Edit OS Menu tab, then after rebooting add it again.

Please post back a screenshot of the maximized Win7 Disk Mgmt drive map and listings.

If XP HD still retains the System Active flags in Disk Mgmt, can you unplug the Win7 HD, enter BIOS setup to set XP HD first HD to boot, then get the XP HD to boot?

If so I would leave it that way, plug back in the Win7 HD to boot via BIOS Boot Menu key. You can remove the XP entry in EasyBCD.

If not then with Win7 HD unplugged try this:
  1. Boot the Windows XP CD
  2. F6 if RAID drivers are required and install when prompted
  3. Repair Windows
  4. Logon to the Recovery Console
  5. fixmbr \Device\HardDisk0 [Enter]
  6. fixboot c: [Enter]
  7. Exit [Enter]
  8. Restart into the OS.
You may finally need an XP Repair Install.

Thanks for reply. I have tried installing Windows 7 with the Windows XP disconnected and than replacing the XP drive and adding Easy BCD-no difference.
I had no problems with XP b4 adding Easy BCD. As mentioned I can selectively boot either one by changing the boot order of the HD in the BIOS. I have not been able to do selective booting with Easy BCD.

Attached are screen shots of the disc management drive map as well as that of Easy BCD

I gave you a series of steps to try and instead you tried something altogether different. If you were going to reinstall Win7 you should have left XP plugged in since Win7 installer will configure a Dual Boot menu when it's installed last.

Your first post also said XP wasn't booting but now you post back a screenshot of XP DIsk Mgmt and what appears to be EasyBCD output from XP.

After reinstalling Win7 did you install EasyBCD to try to add XP, accept offered boot files, let it autocomplete and then reboot? Make sure the drive letter for each OS shown are correct, or Edit the entry to delete and then Add it again.

If that fails then I would boot the choice of OS's via the BIOS boot order and Asus F8 boot menu keys, removing any faulty entries using EasyBCD Edit OS menu.

Make sure the drive letters for the OS entries are correct. If not, edit the entry to delete it and Add it again forcing the correct drive letter.

Try running EasyBCD from Win7 which works better. The steps are given to start Win7 many times in these comments.
