12.04 Beta 2 fails to complete if there's a .iso copy on another partition

[jerrylamos]

Zsync'd today's 12.04 March 25 in a directory on /dev/sda5. Pangolin Beta1 installed opn /dev/sda5.
Copied Beta 2 iso to USB flash memory
Booted Beta 2 iso from the USB flash memory
Ran install to /dev/sda12. There's Windoze 7, Meerkat, Pangolin Beta 1 installed on other partitions.
At almost the end of install:
Warning - (something) mounted on /dev/sda5, please close the application!
(Ubiquity was complaining about the zsync'd precise-desktop-i386.iso. I did not boot that .iso, I booted the one on the USB. No reason for ubiquity to be even referencing that file.)
No way would install complete.
Rebooted, grub had not been run.
Booted the Beta 1 and ran grub
Booted the Beta 2
Strange, grub.cfg shows 3 consecutive entries for the Beta 2:

...
menuentry "Ubuntu precise (development branch) (12.04) (on /dev/sda11)" --class gnu-linux --class gnu --class os {
        insmod part_msdos
        insmod ext2
        set root='(hd0,msdos11)'
        search --no-floppy --fs-uuid --set=root 7d27b84d-35c4-430c-a213-8fd4e7c95c56
        linux /vmlinuz root=/dev/sda11
}
menuentry "Ubuntu precise (development branch) (12.04) (on /dev/sda11)" --class gnu-linux --class gnu --class os {
        insmod part_msdos
        insmod ext2
        set root='(hd0,msdos11)'
        search --no-floppy --fs-uuid --set=root 7d27b84d-35c4-430c-a213-8fd4e7c95c56
        linux /boot/vmlinuz-3.2.0-20-generic-pae root=/dev/sda11
}
menuentry "Ubuntu precise (development branch) (12.04) (on /dev/sda11)" --class gnu-linux --class gnu --class os {
        insmod part_msdos
        insmod ext2
        set root='(hd0,msdos11)'
        search --no-floppy --fs-uuid --set=root 7d27b84d-35c4-430c-a213-8fd4e7c95c56
        linux /vmlinuz root=/dev/sda11
}
...

No entry for recovery mode.

Probably because ubiquity didn't complete, Beta 2 came up, the "install" icon was still on the launcher.

Not a showstopper only because I had other bootable partitions on the hard drive so I could recover the Beta 2 failure to run grub.

This Beta 2 bug has occured on my Acer Aspire 1 notebook and on my Compaq Presario tower.
