Near the end of the reinstallation process, the thing stopped.

[Rickterbeek]

Like all my other bug reports, I have no idea what happened.

I included the log file, though, I'm not sure if that's of any use.

All the information I could gather from my laptop:
Samsung Series 3 355V5C
AMD A6 4400M 2.7GHz with integrated Radeon Graphics
6GB RAM
500GB HDD

(I don't think those last two really matter, but, well, I'm pretty stupid, so I thought I should include them anyway.)

It looks like your disk (sdb) has a number of file systems on it, and from the log it shows that grub failed to install, and there are a number of file system errors. Is it possible for you to retry the install using the entire drive and deleting the bad partitions?

[Rickterbeek (rickterbeek)]

I ordered Ubuntu to reinstall 13.04 while deleting all files, programmes etc. while this problem occurred.
I wouldn't mind deleting the bad partitions (including all files on it: I've made a back-up for those), though, no matter what, but is there a save way to do this? I don't want to mess up everything even more by just trying some things out, haha.
I really need my Windows 8 partition, so I don't think I can use the entire drive (if that's what you mean by it)

Thanks for helping me out, by the way! And holy shit you are smart for finding all that information out of the log files.

Your EFI system partition is corrupt. You will need to repair it with chkdsk in windows, or dosfsck in linux.
