Re: XP & Ubuntu via Wubi
Wubi creates a file on the XP partition that is uses as a hd.
Ubuntu can mount NTFS FS and wubi makes it automount to /host.
Result: XP FS can be accessed via /host in ubuntu
But XP doesn't know how to work with ext* fs or how to mount a file anyhow.
Result: No ubuntu access from XP
This results in your "problem".
PS. The dir in C: is where wubi stashed ubuntu's root.disk and boot files (the root.disk is that hd-file)
I could give you the full technical explanation if you want,
but that's for advanced users/geeks only.
