Can't get passed the partitioning step while installing Xubuntu on iMac

I have an iMac and I fear it is corrupted. When I try to open it, it shows a question mark alternating with a smiley.

• Model Family: iMac G5
• Processor: 1.8GHz G5 (PowerPC 970fx)
• Manufacturer: Motorola
• # of CPUs: 1
• Resolution: 1440x900
• Backlight: CCFL
• Base Memory: 256MB PC3200 DIMM
• Max Memory: 2GB
• # of Memory Slots: 2
• Brand: Apple
• Original OS: Mac OS X 10.3.5

I think it's vintage 😉, but I still want to fix it. First, I think the hard drive is broken (pretty much corrupted), but I tried to install a Xubuntu OS on it because I don't have any other disc. Alas, I think Xubuntu is not compatible because I can't seem to get passed the partitioning step.

Solution 1:

The page is hard to find but Ubuntu has versions specially for MACs. I have included the link, the second one down is listed as

Mac (PowerPC) and IBM-PPC (POWER5) desktop CD

For Apple Macintosh G3, G4, and G5 computers, including iBooks and PowerBooks as well as IBM OpenPower machines.

There are others listed just for MACs. I honestly have no personal experience with these so I don't know if they will work, I was just able to dig into Ubuntu's website deep enough to find the link for you. Hope it helps

HERE IS THE LINK

Note: As I don't know your location I gave you the United States mirrors in the above link I also included 12.04 as it is the newest, let me know it you want another...
