Hi, so here's the case. I know there has been a lot of threads about this but I think I know why this happened but I don't know how to fix it.
So okay, here's what happened:
Recently, I upgraded my OS from Windows XP to Windows 7 Ultimate. However my Windows XP is in Local Disk C: while my Windows 7 is in Local Disk D:. Ever since, I had a dual boot menu at startup. Since I don't plan on ever using my Windows XP, I tried formatting Local Disk C: but it won't let me. So, since i need memory, I decided to delete the files individually including its BOOT folder. It was working until it restarted and told me that BOOTMGR is missing. any hints?
PS: i don't have my windows 7 installer anymore since the CD broke. though I have copy in a USB.
