When I start the computer it first shows the Dell logo then goes to a black screen with the following: Primary drive not found... Alert! OS Instal Mode Enabled. Amount of available memory limited to 256MB. Strike the F1 ket to continue, F2 to run the setup utility.
It is a Dell OptiPlex GX270 with 1Mb ram and 240HD with Windows Vista Home Edition installed which was an upgrade from factory installed Windows XP. I do not have the Windows XP CD.
When I strike F1 it says... strike F1 to retry reboot, F2 for setup utility.
When I strike the F1 again and it repeats the above. etc. etc.
I purchased a program called 'the Emergency System Recovery Boot CD 4.X" but when it is booted up with the CD and strike the F1 key it says: boot: cannot read Master Boot Record. Boot: When I press Enter it goes to a blue screen for the Ultimate Boot CD V4.1.1 with the following choices:
Mainboard Tools
Hard Disk Tools
Filesystem Tools
Other Tools
User-defined Tools
DOS/Linux Boot Disks
*Boot First Hard Disk
*Boot Second Hard Disk
Please Help! I do not know what to do from here.
