Common causes of "Invalid drive specification" messages.

There are several sets of circumstances that can return this status. A. If the drive has not been partitioned (with FDISK) this message will be reported. B. If the drive parameters (Cyl, Hd, Sec) set in CMOS DON'T match those of the drive this message will be returned indicating that the drive geometry read from the drive doesn't match what is entered in CMOS. C. General hardware failure on the disk sub-system where the drive geometry cannot be read (causing the mismatch described in B). This could be a bad cable, misplaced cable (off by a pin or row) no DC power to the disk, bad disk PCB, incorrect jumpering on disk PCB. Any matter of problems that can cause the disk to be unreadable can return this error message. NOTE!! On initial HDD install/upgrade I'd do a physical check on all the obvious things like cable placement, power connectors, listen to hear the disk seeking during it's POST test on pwr up. If this error occurs after the disk has b

Error Message: Disk Boot failure

If your computer has just been formatted, your computer might require you to insert the boot CD to be able to run it. You might hence get the error message “Disk Boot Failure- Insert disk and press enter” displayed on the screen every time you will try to run it. This might be linked to: 1. The boot options not correctly set in BIOS 2. A non bootable CD is found in your CD drive 3. You do not possess any bootable device 4. You have installed a new hard disk 5. The hard disk is not properly plugged 6. Your system files have been infected Solution 1: Ensure that your drives are empty If there is a non bootable CD or disk in the drives, your computer might be attempting to boot the program with this disk. Hence, ensure that the floppy disk drive, the CD/R and DVD drives are all empty before restarting your computer and trying to run computer again. Solution 2: BIOS set up If this has not solved the problem, it might be linked to a wrong set up of BIOS. Hence, 1. To enter
