I recently fitted an extra IDE 60GB HDD to my computer to use as backup. My main HDD is a sata 300GB so I was not certain that it would recognise the IDE one. I was pleasantly surprised therefore that it did and given the letter E. Using the Vista backup program I backed up some important files and set it to backup once a week. This worked well for a couple of weeks until suddenly the computer refused to bootup displaying the message ''No MBR Found'' the only way to get it to bootup now is to disconnect the IDE HDD, any ideas?

Do a repair by putting your vista disc in or recovery disc and select the dvd drive as the boot drive and then select repair option and it should repair it that way you will be able to boot into vista. Jim R

Dear Beginner1...thank you for your welcome advice. I am probably being stupid here but I am not sure I understand what you mean when you say that I will be able to boot into vista. At the moment I am using the SATA HDD on its own and everything works perfectly, it is only when I connect up the additional IDE HDD that it refuses to bootup. Do you mean that after carrying out your instructions I should be able to bootup with both SATA and IDE HDDs installed?.

I think Beginner1 is suggesting using the 'Startup Repair' option when you boot from the Vista DVD and choose repair.

I'm not sure what's changed.... but you could double check your BIOS boot settings... it seems your PC thinks that your IDE drive is the main boot drive when it's connected.... when it's the SATA drive that really is. You could try making your IDE drive a slave... or in the BIOS you might have an option for which drive is the main boot drive or something close to it. TK.

Frequently when adding IDE drives to a SATA system BIOS gets confused and tries to set the IDE drive as the boot one. When I add one I have to go into BIOS and reset the hard drive boot value to the SATA drive. Richard

Yes Richard, that is exactly what was wrong. I went into the Bios where HDD-0 was set as the boot drive and changed it to the SATA, problem solved. Many thanks to everyone for your interest, it has been appreciated.
