I have two OSes installed in my computer. - Windows XP Professional - Windows 7 Ultimate (Release Candidate 1/Build 7100)
I used the Windows 7 boot loader by default to choose between OSes.
When I was using my WinXP, my computer gets lagged suddenly and continuously, and the only way to fix it is by repair-installing it (because I've experienced this many times before, but without W7 installed).
Everything goes OK. But when my XP was successfully reinstalled, I cannot boot my Windows 7 anymore. Every time I tried to boot the harddisk that contains W7, an error appeared. "TMGR is Missing".
Now I have no idea how can I get back to my Windows 7.
Any kind of help would be appreciated! :)
