Take the 2-minute tour ×  On an old netbook I have which is
(was) running Windows XP, and when I boot, I get a BOOTMGR is
missing error, but according to this site I should actually get
NTLDR is missing instead. I find this vexing. Is there a fix for
it? (Exact error: BOOTMGR is missing (newline) Press
Ctrl+Alt+Del to restart)  share|improve this question Does the
drive appear in the bios IDE menu pages? If this happened
randomly, without any software changes, it's likely the hard
drive isn't visible to the bios - either because of loose cables
(like the link mentions) or a physically damaged drive. If you
can boot from a USB CD/DVD drive, and you know the hard drive is
physically ok, you can fix the boot files using a windows
install CD in recovery mode. –  jdh Jan 2 '13 at 15:53  1 Answer
