[H] Extend partition?

[DHSinclair]

Been studying the Disk Manager in XP.  I would dearly like to extend my 
current c:\ partition to now span the remaining 4.27GB on the hard 
drive.  Last night I backed up and got rid of the d:\ partition on the same 
drive.  So, now I have my c:\ partition (system) at 4.27GB, and an 
Unallocated 4.27GB space on the same drive.

Reading the details of the Disk Manager, and, buried deep in the 
directions, it says the EXTEND command will NOT allow extending a 
system/boot partition!  Huh?  Anyone know why this is so?

I suspect that the MBR may get dorked up and/or I may have to use the 
Repair Console again to do a CHKDSK c: /R followed by the bootcfg /rebuild 
commands .... (well if it worked........ :)

I do have a variety of disk partition tools here, but none will play on a 
full U160 scsi system!  And, I do hot have a spare pata CDROM to swap into 
the system....... :(
Thanks,
