Windows 7: Dual boot not working

Before installing Windows 7 I was running a dual boot XP Pro set up with each copy of XP being on it’s own disc drive. I installed Windows 7 on one of my discs over the top of the XP system. Windows 7 runs fine but the copy of XP on the other drive does not boot. At startup time after I select XP in the boot menu, I get the following error messages:
Windows could not start because of a computer disc hardware problem.
Could not read from the selected disc.

I then went to the link below and did Part 2 steps 8-11. I got the same error messages. I know there is no problem with the XP disc because I recovered the XP partition on disc 1 and was able to boot up the other XP system ok

Any suggestions? Help please.

Please post a screenshot of your Windows 7 Disk Management map.

I hope this is the disc map you wanted.

I forgot to mention that Win 7 is installed on drive C. XP Pro is installed in drive F.

You can try booting the xp disk and do a repair or install boot loader. I had no problem, Running 7.vista.xp.Mac.

What ever you boot becomes C:

I believe the F:Games drive which is also marked active is complicating Windows 7 normal ability to configure a boot menu.

Unplug all drives except your XP and Windows 7, boot into Windows 7 drive and run a Repair install which will reconfigure the boot correctly. A repair install in Windows 7 is an Upgrade install over itself, which leaves programs, files and settings in place but reinstalls the OS and freshly configures the boot.

If unplugging your data drives causes you to lose the ability to boot Windows 7, run startup repair from the Windows 7 installer repeatedly until it boots.

Please also post back here which drive is set to boot first in BIOS.

Without having seen the bcd entries - you could try this:

Open an elevated command prompt and type:

bcdedit /set {ntldr} device partition=F:

then press enter

SIW2: His 7 drive should be set to boot first in BIOS, correct? Even if the XP is holding the MBR?

Not necessarily.

At this point - it looks like he should be able to get XP booting with correct bcd entries.

Assuming the Xp boot files are in good shape.
