Wubi fails to boot after 14.04 install on HP Mini 110-3700

[Walter_Wittel]

On a fresh Wubi install on an HP Mini 110-3700 with Atom N455 1.66GHz, 2.00 GB RAM, 32-bit Windows 7 Starter, on reboot I get the message:

"Serious errors were found while checking the disk drive for /."

If I press S to skip mounting I get a logon prompt and can use the installed user name / pw to browse the file system.

I've attached the logs from /var/log/installer. I'll leave the system in this state for awhile if you need more info.

NOTES:
* I ran Wubi after copying to the Win7 desktop from a *32-bit* Ubuntu 14.04
* No problems noted during install, except seemed strange that Wubi was downloading an x64 torrent
* I can boot on this machine from a USB Startup disk of both ubuntu-14.04-desktop-amd64.iso and ubuntu-14.04-desktop-i386.iso
* I got exactly the same symptoms on reboot after upgrading 13.10 (original Wubi install upgraded several times) to 14.04 (from the ubuntu-14.04-desktop-i386.iso image). I saved the root.disk from the upgrade so could mount it and provide log files from that if it would be helpful.

I ran into this when upgrading from 12.04 to 14.04 64 bit. Neither the release notes nor the upgrade instructions mention Wubi.

From the "Serious errors were found" prompt I went to manually check the filesystem, /host/ubuntu/disks/root.disk which turned out to be clean. Following some forum suggestions I edited the boot command line in grub to use 'rw' instead of 'ro' which allows boot to complete. Editing /etc/grub.d/10_lupin and running update-grub makes the change permanent so I can keep on booting. I don't know enough about the Wubi boot process to know if this is fixing the root cause or just a nasty workaround that could have unintended consequences.
