Reinstall MacOs on Grub GNU

I had luck with Drive Genius but you do have a bit of a problem here as this newer version won't run under Snow Leopard ;-{ Give ProSoft a call to see if they can offer you a version that will work. Or, take the drive out and use a newer Mac externally or using Target Disk mode to connect it too.

Or even use a Windows PC to scrub the drive down using their disk tools FDISK & FORMAT on the command line.

Is Ext4 ok for macos? Or should I use FAT?

No other option suggested from windows and Linux

If you are using a Windows PC to scrub the drive just use FAT32 or exFAT. Once you put the drive back into the Mac you'll need to redo it back the GUID & Mac OS Extended (Journaled)

Thank you @danj .

For last, do you know of there is any software that can format to MacOs Extended form Windows?

The thing is that I have formatted the disc to exFAT and I cannot install MacOs. I always get that "prohibited" symbol. I guess that this could be related.

@mrngview , if you are able to boot off the DL DVD for the Snow Leopard installer, at the top of the installer's Finder, there should be a "Utilies" menu containing "Disk Utility". You can use this to format to Mac OS Extended Journaled. Remember to change it to GPT (vs mbr) first.

@avanteguarde - Sounds like he doesn't even have the OS install disks.
