Thread: Wubi Install - Cannot Find Root - XP exFat Encryption?

after did wubi installed had problem below. install on windows xp laptop may encrypted. boot manager sophos (security manager) recognize new entry , provides me option select ubuntu. however, after selecting ubuntu following:


gave waiting root device. common problems:
-boot args (cat /proc/cmdline)
-check rootdelay= (did system wait long enough?)
-check root= (did system wait right device?)
-missing modules (cat /proc/modules; ls /dev)
alert! /dev/sdb1 not exist. dropping shell!
(initramfs)

there suggestions hard drive inaccurately set in ubuntu .mbr , should reset manually. fair enough. since booting sophos , not grub not use esc, insert, 'e' sequence. did find wubildr.mbr , wubildr files in c:\ root directory binary.

used livecd not find hard drive (history below). not sure if because of hpfs/ntfs/exfat or because harddrive may encrypted.

did find reference dealing filetype (http://stackoverflow.com/questions/6...n-ubuntu-11-04) before dig deeper figured push out there , see if there's suggestions before spend more time.

1. there way change mdr file (presumably on assumption problem)? copy ubuntu system if there's editor use.
2. encryption going cause problem bringing ubuntu @ all?
3. better off deleting wubi , going separate partition? sophos / encryption still issue?




history

using livecd , trying force mount of /dev/sda1 gives me errors.

maybe wrong device used? or whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? or other way around?

(so tried sda1)...

@ point went on read hpfs/ntfs/exfat support , potential issue encryption.

in general not going able boot wubi install disk image file lives on encrypted ntfs partition, because neither boot loader (e.g. grub) nor linux kernel able use windows driver decrypt ntfs partition.

can work in these circumstances is:
* decrypt ntfs
* shrink ntfs , make linux partitions root, swap , else want in resulting free space
* re-encrypt ntfs
* install linux, putting boot loader on linux root (or boot, if separate) partition)
* install boot manager on windows such easybcd neosmart.net, , add linux partition windows boot menu
