Re: Dual booting in DOS(Windows) and CP/M-86

BOOTANY appears to be a nice utility, however I did find one problem with
it. Once installed it CAN'T be un-installed! The only way to get rid of it
is to do a low level format of the hard disk. This was possible on MFM
drives but not on IDE drives. Even running FDISK and deleting all partitions
won't get rid of it. The program appears to have been written with a real
IBM PC in mind since one of the options is to start the ROM BASIC, which
today's PC's don't have. Will keep trying.

Have you tried "fdisk /mbr" from a DOS boot floppy? I
think the parameter exists from 5.0 on, maybe form 6.0
on I'm not sure. It re-writes the original master boot
record of the HD, so everything should be as before you
had installed BOOTANY.

Thanks. "fdisk /mbr" did the trick. I also found a neat utility on Seagate's
web site called DiskWizard. One of its features is the ability to "zero" out
an entire IDE hard disk. That returns the drive to its original new
configuration.

My luck BOOTANY wasn't so good. The example installation used two versions
of OS2 and MS-DOS 4. I was trying to install MS-DOS 5, 6.22 and CP/M-86 but
it just wouldn't work. I finally settled on version 5 and CP/M-86. I used
"CVV" and got seven 8 Meg drives off the leftovers after install DOS. I want
to be able to run Z80MU310 and that program does strange things on DOS 6 or
higher.

Anyway, Thanks for all the help. BTW, I've got a Kaypro 10 coming on Monday
so it looks like I will be up to my ears in CP/M in a few days. :-)

Did you try FDISK /mbr?

I did and it worked.
