I tried installing today and ran into quite a number of errors.

First one:
"Error!!!
Error informing the kernel about modifications to partition /dev/sda1 -- Device or resource busy. This means Linux wont know about any changes you made to /dev/sda1 until you reboot -- so you shouldn't mount it or use it in any way before rebooting."

I selected "Ignore"

Second one:
"Error!!!
Error informing the kernel about modifications to partition /dev/sda5 -- Device or resource busy. This means Linux wont know about any changes you made to /dev/sda5 until you reboot -- so you shouldn't mount it or use it in any way before rebooting."

I selected "Ignore"

Third one:
"ailed [it really says ailed, not failed] to create a file system (as superuse"
The ext4 file system creation in partition #1 of SCSI1 (0,0,0)(sda) failed."

I selected the only option, "OK"

It then looped back to the prepare disk space screen
