BOOTMGR is missing...
Posted on 2010-08-14
I have recently purchased a SSD hard disk. I first set my BIOS to AHCI and then proceeded to install Windows 7 64-bit.
The drive performs fantastically, it is lightning fast.
BUT, if I switch the computer off and then on again the SSD is not being detected by the BIOS and I am given a message stating that no boot drive could be found. When I go into the BIOS you can see that the DVD-RW has been detected, but the SSD is nowhere to be seen.
If I switch the computer off at the mains and wait a few minutes, and then switch it back on again the BIOS detects the SSD and Windows start up perfectly.
Sometimes I get the more alarming message "BOOTMGR is missing". When this happens a cold boot is not the cure... Instead I have to switch from AHCI back to IDE and then it will boot into Windows again. I then restart the computer and switch it straight back to AHCI and it works fine again (until the next time).
The same problem also occurs when Windows goes into sleep mode (though sometimes Windows does actually recover from sleep mode).
I have a Corsair Reactor 60GB.
