Fixing PBR Label Alerts
Opening a partition (logical volume)
Use PTS Disk Editor (de.exe) or a similar utility to edit the partition
boot record of the first and third partitions. Boot from a DOS boot disk
and launch de.exe. On the left side of the opening screen, choose to select
from Partitions, then on the right side select which partition.
If the first partition is still marked 'DE', it will probably show as
"Unknown" here, but you should be able to identify it by its size,
which is usually around 30-60 MB.
The third partition should show as "FAT32" (if descriptor type is '0C')
or "CTOS" (if descriptor type is 'DB').
DellUtility partition boot record
Open sector 1 of the first partition. This is PBR 1. The partition label
consists of 11 bytes from offset 002B-0035h (shown highlighted in this
figure), right before a 'FAT16' string of characters.
Pressing the
Tab key allows you to alternate
between editing the raw bytes on the left side, or the ASCII translations
on the right side.
Press
Tab so the cursor is on the right-side
part of the display, then move the cursor to the area where the label
is supposed to be.
Type '
DellUtility', using both uppercase and lowercase letters.
When leaving the sector, you will be prompted to save the changes.
DellRestore partition boot record
Open sector 1 of the third partition. This is PBR 3. The partition label
consists of 11 bytes from offset 0047-0051h (shown highlighted in this
figure), right before a 'FAT32' string of characters.
Press
Tab so the cursor is on the right-side
part of the display, then move the cursor to the area where the label
is supposed to be.
Type '
DellRestore', using both uppercase and lowercase letters.
When leaving the sector, you will be prompted to save the changes.
