I would like to do the install from an ISO file because it is so fast
and convenient compared to using a DVD.

I successfully booted from a Mint-14 ISO-file.
The install started fine, but I soon got this message:

The installer needs to commit changes to partition tables,
but cannot do so because partitions on the following mount points
could not be unmounted: /isodevice
Please close any applications using these mount points.
Would you like the installer to try to unmount these partitions again?

There were two buttons: [goback] [continue]
and also an [x] in the upper right corner of the message window.
With all choices it just sat there.

This is especially surprising since my ISO file is on a completely separate
hard disk from where the installation was being done, so I wouldn't expect
its partition table should possibly be changed here.
It seems that the logic here is simplistic and/or overly cautious.

Last system I installed was Ubuntu 10.04 and it worked fine from an ISO file.

For more completeness, here's my Grub2 entry:

Code: Select all

menuentry "> ISO Mint-14.1 Cinnamon - Nadia - ISO (sdb6) <" {
   search --no-floppy --set=isodisk --label data2
   set isofile="/iso/linuxmint-14.1-cinnamon-dvd-64bit.iso"
   loopback loop ($isodisk)$isofile
   linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=$isofile noprompt
   initrd (loop)/casper/initrd.lz
}

Of course, this is not a show-stopper since I was able to install from DVD,
but I would rather use a hard-disk if possible.
- Any insights or ideas appreciated.
- If this seems like a bug, what's my next step?

Thanks,
LenW
