Hi,

I am attempting to install 10.10 from the iso because I have no working cdrom. I uncompressed the .iso to a ext3 partitions and put the correct entries in the menu.lst file. It starts ok. The problem occurs when I attempt to install to the hard drive. At a point I get the error,

Failed to unmount partitions
The installer needs to commit changes to the partition tables, but cannot do so because partitions on the following mount points
could not be unmounted.

/cdrom

I have a choice of continue or go back. If I continue the install hangs. If I go back I cannot continue. How do I fix this problem? Thanks.

I don't think you need to extract everything from the ISO file. You'll need the alternate ISO file not the usual one.

Here are some instructions:
