This has happened twice to me today. The first time I'm not quite sure if I was doing the same thing as I was the second but it's pretty likely I was. Here goes.
I did a restore on my computer from Norton Ghost. It was just an image with the bare nessesities - Win ME, mobo drivers, card drivers, etc. It also had Partition Magic 6.0 and Norton Systemworks 2002 installed. It did the restore perfectly. When it was done, I popped out the cd and rebooted without any problems.
I did all of the Windoze updates, partitioned the drive into the following partitions:
c: Win ME - 3.5GB
d: Win 2k Server - 3.5GB
e: Win XP Home - 3.5GB
Linux partition 4GB
Linux swap 256MB
Remainder for Data and programs.
That also went ok. I didn't install anything on the partitions.
(o/s's, etc.) I booted back to ME after partition magic did it's thing and started my tweaks. Among one of the is I set the swap file to the slave drive (Maxtor 60GB) for a minimum of 160mb to max at 512mb.
I then started running through Norton Systemworks to make sure everything was going good with ME before moving on to 2K. I ran Disk Optimization and it said something about optimizing the swap file with it and to reboot - I "yes"ed it and rebooted.
Invalid system disk. As I said, I did the same twice today

. I'm suspecting either the swap file tweak (a new one to me but it worked fine 'til I ran Norton Speed Disk / Optimization) or it's Norton speed disk.
Here's the specs:
Asus A7A266
XP 1700
512MB PC2100 DDR Ram
40GB Maxtor 7200 rpm master
60GB Maxtor
20x10x40 Lite On CDRW
16x Sony DVD,
etc.
Any suggestions? Both drives are about 5 months old and I have always had great luck with the Maxtor drives.
If I boot to a 98 boot disk, I see everything on C drive. I'm guessing something happened to Windows. I didn't have a third party boot proggie going (Boot Magic). Anyway to restore the boot record / swap file. I 'm lost on this one.
Thanks in advance,
Mike
