iM 4,1-14,4 I've screwed up an Early 2008 iMac HD: diskmanagment .disenter error 49180 impossible to mount the disk

Hi there,

I'm pretty sure I'm not the first to reach out with this problem and I do not know if there is any solution other than change the disk. I appreciate any input you can provide and also I would like to know if there is any "bootable" usb solution able to format and mount the disk as with utility disk it is just impossible. Thanks in advance and Happy new year to everybody!

Disk utility is present on any retail disk image. Put the installer image on a flash drive & stick it in the Mac’s usb port, Start the Mac holding the option key after the chime which will bring up the boot picker. Choose the usb and the Mac will boot into the installer. Choose utilities at screen top and then disk utility. There it should see your borked drive and you should be able to reformat & partition the drive for fresh macOS install assuming the drive is not broken/dead. If that’s the case, you’ll need to pull the glass off, remove the lcd and then you’ll have access to the drive caddy where you can install a new SSD ready for fresh macOS.
