64 bit ubuntu doesn't boot

What are the contents of the C:\boot.ini file?

I don't see that file in C:. Only autoexec.bat and config.sys

It's hidden. Here's some reference material from Microsoft: http://support.microsoft.com/kb/289022

I found it. There is no reference to ibuntu though. Here is content of the
file:

multi(0)disk(0)rdisk(0)partition(1)WINDOWS="Windows XP Professional x64
Edition" /noexecute=optin /fastdetect /usepmtimer

Sorry for the delay... that doesn't look like a well-formed boot.ini - maybe that is why the update failed. It should look like this:
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)WINDOWS="Windows XP Professional x64 Edition" /noexecute=optin /fastdetect /usepmtimer

If that is actually how it looks, you can add an entry for Ubuntu yourself. I'm not sure why it didn't get added. If this is the only problem it should work, but be careful editing boot.ini. If you make a mistake you may have booting problems (or get a hal.dll error).

The entry should be:
C:\wubildr.mbr="Ubuntu"

So the whole file looks like
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)WINDOWS="Windows XP Professional x64 Edition" /noexecute=optin /fastdetect /usepmtimer
C:\wubildr.mbr="Ubuntu"

If you prefer to troubleshoot and try reinstalling you can copy the wubi log file from the %temp% directory to http://pastebin.ubuntu.com and return the address here and I'll take a look. I'm not sure why this happens on the rare occasion.
