Вот совет от производителей. Была похожая ситуация (не у меня). Попробуй разобраться, может поможет.
[pre]To fix a PQRP with PTEDIT:

1. Run PTEDIT.
2.  Locate  the  PQRP  (partition  type 3C). If the PQRP occurred on a
logical partition, click "GoToEPBR" to locate the correct partition.
3. Click in the "Type" field associated with the 3C partition.
4. Click "Set Type." A list of available partition types is displayed.
5. Select the appropriate partition type (e.g., FAT32 if the partition
type was FAT32 before the PQRP, etc.).
6. Save the changes and exit.

If  the  system  does not boot properly at this point, run a directory
listing  (DIR)  on  the  drive  and  make sure there are no "DYN_ROOT"
entries.  A  "DYN_ROOT" indicates that the original root directory has
been  relocated  but can, in most cases, be restored. If the directory
listing appears as random ASCII code or unrecognizable characters, the
partition is likely corrupt and cannot be recovered.

Note:  If  the  root  directory  appears as a DYN_ROOT, do not SYS the
drive.  Modifications made to the drive while in this state can reduce
the  probability of recovery. Contact PowerQuest Technical Support for
further assistance.
