Windows 7: Dual Boot: Cannot "see" data partition

02 Jan 2010   #11


I can boot up on this single disk to XP only, I do see the Dual Boot screen come up, but the Win7 does not load, saying "...cannot find...."

cannot find what?

Does it say this:

“The boot selection failed because a required device is inaccessible.”

Wait, I got that "..could not find..." when i booted up on the other drive.

With this drive shown, that has the XP/Win 7 os's, it only goes straight to the XP os.

So that means the dual boot .ini is on the other drive liked you said at first. I do have a Boot Manager application, so I could use that to possibly reconfigure (?)

IF i just reinstalled Win7 currently , would this not just add the proper dual boot.ini?

thanks for assistance

Suggest you try Easy BCD 2.0 to configure the dual boot from XP.

why not just Reinstall win7?

Will a re-install of win7 not do the trick?

EasyBCD or repair install is less trouble.

3 files: only on XP os.

The 3 files are ONLY in the root of the C:\ XP os.

My thinking is if i copy them to the F:\ WIN7 os, how does this create the dual boot.ini that is obviously on the other drive the i have disconnected now?


Again, I have that EasyDCD application that SHOULD recreate the Dual Boot environment should it now?

Yes you'll need to install Net Framework 2.0 to run Easy BCD in XP.

Use Easy 2.0 which is automated: Attachment 45297

Confirm the listings are correct by using the Change or Add/Remove tabs if necessary.

I would personally boot Win7 DVD to run Startup Repair 3 times to rewrite the MBR to Win7, then either add Vista using EasyBCD or run a Repair Install from Win7 to reconfigure the dual boot.

If you don't care about saving Win7 install you have then you could also reinstall.
