Deleted dual boot partition

[Inikay]

Hi!

I had a computer with windows XP in an older Disc and Windows 7 on a newer one. Windows 7 was installed after windows XP.

On startup, I got the dual boot screen, and I could choose between both.

I didn't want the old windows XP, so I formatted that old disk. Result: no boot now from windows 7... I read on Microsoft website that I shouldn't have done that, since the PC uses the startup files from the older operative system to start the computer on a dual boot.

Now, what can I do to make my Windows 7 installation work? The Hard Drive has everything untouched, of course, and all my files are there. I can always install it again and move my files, but that's a lot of work.

Is there any solution?

Thanks.

Win 7 doesn't use boot.ini like XP did it uses information on the bootsector which likely was overwritten. You need to fix that part and should be alright using bootrec:

Thanks Motorheader. Solved it using a bootable Minitool Partition Wizard to set the drive as active and then Windows startup Repair did the rest.

Thanks for your help, nonetheless.
