Hi, I am a relative newcomer to Linux (ran it on an old Mac for a while a couple of years ago). I recently came into possession (legally, shame on you!) of a Toshiba Satellite A205 S5804, and Vista Home Premium is such a dog on it that it seemed a perfect time to play around with Ubuntu again. So I downloaded the i386 8.10 iso, burned it to disk, and booted up, after having done a total wipe and reinstall of Vista from the Toshiba recovery CDs. The 8.10 LiveCD works very nice.
I had planned ahead and installed Vista into a 40GB partition during the Toshiba recovery install process, leaving 70GB for Ubuntu. However, when I get to step 4 of the Ubuntu LiveCD install process the partition table is totally blank, and all the buttons are greyed out. I can't go forward to step 5.
So, I bail on the install, and poke around by looking at the properties of the NTFS drive visible on the Ubuntu desktop. The NTFS Vista partition really is 40GB in size, as seen under Linux.
I did some googling, and one recommendation I saw was to run GParted. Luckily it is available on the LiveCD, so I fire it up. It runs OK, and says that there are four partitions: unallocated 1MiB, 1.46GiB Toshiba System Volume, the 40GiB Vista partition, and then 70.32 unallocated, more or less as I expected. I tried assigning that last unallocated partition to an ext3 filesystem, but re-running the installer still gave me the blank table again. So I set it back to unallocated with GParted.
So, more searching in the forums... I saw that CalJohnSmith had helped someone with a corrupted partition table; maybe that is what I'm dealing with? The info he requested is here:
I also a forum posting where ElizabethJoan had a somewhat similar problem that appeared to be related the fact that she had a SATA disk (which the A205 has, also). CalJohnSmith, are you out there? What do you recommend?
