I have two os's in my internal drive, a windows 7 and an xp. Now my brother owned a laptop but no hdd's so i bought a new drive and installed in my pc so i can install an os to it (i used my pc because there is also no cd rom drives in the laptop) i finished installing the os, which is windows xp by the way. Now i know that shouldn't have installed an older version of windows after installing a newer one, but i didnt know that it was gonna write the boot files on the drive i booted from, i thought it was going to write the boot files on the destination drive. so now bootmanager only sees two os's, the old xp and the new xp but no window 7.
is there something i could do to restore the old boot files?
can anyone help me pleease ( i'd be forever grateful
