Description Jeff 2001-03-15 09:11:09 EST
From Bugzilla Helper:
User-Agent: Mozilla/4.76 [en] (Win98; U)

I had a disk partitioned in Win9x.  I cleared off one of the partitions, but didn't delete the partition.
When I went to install RH7, I chose the fdisk partitioning, chose the proper drive to partition, and
realized that I didn't know which Win9x partition to delete.  I rebooted into Win98SE and deleted
the partition.  When I went back into the RH7 installation, I chose fdisk partitioning, and the computer
rebooted itself.  This was before it gave me a chance to select the drive.  This happened every time.

Reproducible: Didn't try
Steps to Reproduce:
1.Delete a Logical DOS drive in Win98SE fdisk.  It may be significant that there were other logical partitions; I don't know.
2.Attempt to install Red Hat 7
3.Choose fdisk partitioning

Actual Results:  Immediate reboot without error messages.

Expected Results:  Menu asking which disk to partition.

As a diagnostic, I rebooted from the RH7 CDROM.
I started fdisk in the shell on console 2.  Fdisk did not crash or fail in any way.
When verifying the partition table, it gave the warning:
  Partition 5 is empty
The partitions were listed as 1 (FAT32), 2 (Linux), 3 (Windows Extended (LBA)),
6 (Linux), 7(Linux Swap), 8(FAT32).  In expert mode, partition 5 was listed, but was
empty, with zero start, end, and partition type.  The linux partitions were from a separate
old linux installation that I wish to preserve; Partition 5 is where I wish to install RH7.

After deleting partition 5 (and rebooting), the Red Hat installer allowed me to run fdisk again.
I could create a new linux partition, fix the order (xpert menu 'f'), and install RH7 there.

It appears that the Red Hat installer couldn't handle the empty partition created by deleting
partition 5 in Win98.

Thank you for the report.

I will keep this information around to help other users.
Comment 2 Michael Fulbright 2001-03-23 11:23:37 EST
I've made a change to tell the user when this type of partition has been
detected, and inform them we will not install to this type of drive.  This is an
issue I will try to address in a future release. At least it will not segfault now.
