Check out this number of 512byte sectors: 3,018,063,139 b2 QNX Neutrino Power-Safe (wow!!!!)
(I had previously never even heard of a QNX o/s........ it looks like a case of 'mis-identification'.)
Gparted sees 149 GiB with partitions and files system, both unallocated.
The PC boots to Win XP ..... we've lost the GRUB and access to Xubuntu.
Here's what happened:
During initial setup, a win partition was created for AVG, with the intention of separating the mammoth daily updates.
This was a fail..... AVG simply bypassed this to load on C drive.
So there was some spare capacity right next to the winxp partition.
A partition had been created to install programs, but the user forgot when installing a very big gaming package - crossfire.
(We'd tried to get this to work on xubuntu, but it was always laggy)
With updates, and all, C: ran out of space (I noticed when trying to shut the damned thing down this Monday).
I figured.... shrink the useless AVG partition, and move it to the right, to create space to the left, allowing me to expand the win xp partition.
I guessed that messing with the partitions might rupture GRUB...... but we did have 'BOOT-REPAIR'
Using Xubuntu & GParted:
The first operation was to create free space to the left of the AVG partition.
I clicked through all the warnings (I had boot-repair ready).
The operation failed.
I re-booted to witness the consequences, and had no 'bead of sweat' when I got 'GRUB ERROR'.
I immediately booted to boot-repair, accepting the std config.
Boot-Repair Ditched GRUB and Xubuntu:
On re-boot, instead of a multi-boot menu.... the PC booted directly to win xp.
I figured that I would be able to fix this using the advanced setting, however, when I examined the disk (using boot-repair gparted) the disk was shown as effectively empty.
I then ran the xubuntu install disk (choosing something else) to load GParted....... same result.
I then downloaded GParted Live....... same result.
Bizarrely enough.... the WinXP embedded disk manager sees all partitions, though, as normal, it doesn't understand the xubuntu/swap partitions (even if it sees them)
So For the Moment I'm stuck:
I can't do anything with GParted cos it thinks the disk is blank.
I can't risk, (without support) trying boot-repair's advanced option, in order to try to re-build the GRUB and re-gain xubuntu (and and then subsequently enlarge C: to absorb the (now formatted) ex-AVG partitition).
Thank goodness we have the 'boot-repair output text'.
