I have one drive which has four partitions (because at one time, I planned to try booting four different OS's). It was installed with a boot selector that defaulted to the third partition (partition number 2) -- NetBSD. This has been working since installed in February. At first, all I used was the NetBSD partition; but over time I needed more space, so I used disklabel and started using the other partitions.

I had never used the first partition. Last week, I added a new slice from the first partition and did a newfs -- this worked great and added a lot of needed space.

Today, the first time I rebooted, it would just hang at the boot menu. I am able to boot with the install floppy: "boot wd0a:netbsd".

Some things I have tried include:

fdisk -i
/usr/mdec/installboot -v /usr/mdec/biosboot.sym /dev/rwd0a

I was able to get rid of the menu, but I am not sure what to do to get it to automatically boot from wd0a:netbsd (like it previously did). I also tried creating a new menu -- which I was able to do with:

fdisk -i -c /usr/mdec/mbr_bootsel
fdisk -B

But I couldn't get it to automatically boot from my wd0a slice. (See 18/Dec/2000 and 07/Sep/2001.)
