ok, 'INVALID SYSTEM DISK" on boot up. when i boot from the floppy, the C DRIVE directory just has 4 files with approximately the same file size 500k or so, and the file names are just a single ASCII chracter, no extension. such as: ä 500,976 ÿ 500,543 and so on. windows 98 was loaded on the drive. no other files in the directory other than 4 or 5 similar to the ones listed above. ran ACRONIS RECOVERY EXPERT from a different drive with the affected one as the slave, and ACRONIS said there was no unallocated space found on the drive and terminated. any ideas?
