Boot time is more than one minute with ext3 FS recovery everytime

Question

It takes more than a minute for Ubuntu to boot up on my new laptop. I have Windows 7 and Ubuntu 12.10 installed using Wubi.

From dmesg, I see the following:

[    2.934384] EXT3-fs (loop0): recovery required on readonly filesystem
[    2.934387] EXT3-fs (loop0): write access will be enabled during recovery
[   23.804784] kjournald starting.  Commit interval 5 seconds
[   23.871524] EXT3-fs (loop0): recovery complete
[   23.871526] EXT3-fs (loop0): mounted filesystem with ordered data mode
[   45.069369] Adding 262140k swap on /host/ubuntu/disks/swap.disk.  Priority:-1 extents:1 across:262140k 

Note the big time gap between the entries. You might ask whether I put my computer to a unclean shutdown because of the filesystem recovery, but I just shut it down gracefully using the system menu.

How can I improve the boot time?

That's not normal for Wubi. Mine takes about 4 seconds to load where yours is taking 20.

The key is that your filesystem is marked as corrupted. And if it's doing that every time then whatever fsck is doing is not fixing the problem. So you could fsck it from a live CD and see if it provides any decent output. Or try running chkdsk /f from Windows - as there could be some NTFS corruption as well. Or try reinstalling.

Here's my output for the equivalent operations - and ignore the swap as it uses a partition (also my root.disk is ext4 as it was installed via the ISO but that shouldn't make any difference to the time required to mount it):
