Thanks to MASQUERAID for all of their help so far :-)
On this Dell Windows 3.1 machine, I loaded some program in DOS from the File Manager in Windows (to see what it was, I haven't been on this system in 10+ years), and it was some sort of loop that I couldn't close out of. So I turned off the computer with the power switch. Now when I start it up, it does its POST then says "Missing operating system."
I make sure the hard drive is auto detected through the BIOS, but no go.
Before, it would start to load, and load SCSI controller drivers then CD-ROM drivers, then load the AUTOMENU program I was using to choose either Windows or DOS. Not having the SCSI controller or CD-ROM drivers loading isn't a problem at all, in fact it would be good if they didn't because I don't use the drive anymore and now it just complains it can't find it and I have to press Enter to continuie.
Anyway, I _can_ get into Windows by booting with a DOS 5 bootdisk, then just loading either AUTOMENU or Windows through the command line. And I think I remember the bootdisk saying something about HIMEM.SYS, so I believe that's being loaded too.
Is there a way I can fix this though? I've tried SYS C: from the A: drive, it completed but complained that it couldn't copy COMMAND.COM, so I used attrib to take the read only off of it and it copied over fine, and then put it back on, but that hasn't done anything, still the same error. I made sure in FDISK that it was the primary partition, I did FDISK /mbr, but no go either.
I would just like it to boot like it did before, but if that's not possible, is there a way to modify the bootdisk (I'm using the DOS 5.0 bootdisk from bootdisk.com) so that instead of dumping me just to the A: prompt, it'll load AUTOMENU? That would just be a simple thing of adding in a line, but I don't know where.
Any help is greatly appreciated! Thanks!
