Cannot Access Hard Disk After Booting from Floppy Disk
This article was previously published under Q245162
If this article does not describe your hardware-related issue, please see the following Microsoft Web site to view more articles about hardware:
After you start your computer from a floppy disk for troubleshooting purposes or to install an operating system, you may receive the following error message after you attempt to change to the hard disk, even though the hard disk is correctly partitioned and formatted:
Invalid Drive Specification
This error message can occur if you have a drive overlay program installed
and you do not follow the proper procedures to boot from a floppy disk. When a drive overlay program is loaded, you cannot boot directly from a floppy disk if you want to be able to access the hard disk. You must first load the drive overlay program and then boot from the floppy disk.
To resolve this issue, check the documentation included with your drive overlay software, or contact the hard disk manufacturer for information about how to boot from a floppy disk and access the hard disk.
Drive overlay or geometry translation software may be used when a computer does not support Logical Block Addressing (LBA) for gaining access to hard disks over 528 megabytes (MB) in size. Drive overlay software may also be required when a computer's BIOS does not support INT 13 Extensions to gain access to hard disks larger than 8.0 gigabytes (GB) in size.

Community Feedback System
Very often, it takes hours to solve a problem. Very often, you've looked high
and low, and have tried a lot of solutions. When you finally found it, chances
are, it was because someone else helped you. Here's your chance to give back.
Use our community feedback tool to let others know what worked for you and what
didn't.
Please also understand that the community feedback system is not warranted to be
correct, it's simply a system that we've built to let people try and help each
other. If something in a feedback response doesn't make sense to you, or you're
not comfortable making changes that the feedback talks about (like registry
edits), please consult a professional.
