Similar problem to this thread:
Normally when I start up the computer I get the AMD screen, a few pages of code appear and dispear and I then get a screen asking me to choose between Ubuntu and Windows 7.
Instead after the first screen I get this error message:
Verifying DMI Pool Data ….................
Boot from CD:
DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER
I have used Sim's bootrec.exe/fixmbr and /fixboot instructions that solved the problem last year but this time they have no affect. The only thing that works is the same thing that I temporarily used to fix the problem in 2010/11 - putting the windows disk in at start up and for some reason it boots.
Suggestions? ATM I can't access Ubuntu and having the disk in at start up is only a temporary solution.
