I have followed the Ubuntu windows installer procedure, but after step 7 I get a message from the windows boot manager saying that windows has failed to start and that I should insert a (nonexistent) windows installation disk.
Further on it reports
Info: The selected entry could not be loaded because the application is missing or corrupt.
It appears as though many people are having problems installing Ubuntu along side Windows 8. My problem, however, seems to be sufficiently different to be unique among such problems. I can't get the Ubuntu 12.10 live-USB installer to run. When I boot I get the following four options:
Run from this USB
Install to disk
(I can't remember the last one)
