ubiquity package

installer crash during grub

Asked by Kevin

I have an Acer Aspire S7-391 running Windows 8.1.

I partitioned 1 GB for EFI, 4 GB for swag and 10 GB for the Ubuntu installation. When I attempt to install Ubuntu 14.04.01 off a flash drive, the installer crashes when it comes to installing grub. Do I need different partitions or to partition my hard drive differently?

Thanks

I have also disabled Secure Boot and turned off Fast Startup on Windows 8.1

Did you MD5 test the ISO you downloaded?

So I just MD5 tested the ISO and the checksums are not equal. Does this mean I have to redownload the ISO? Also, is there a way I can do the checksum once I've put it on a Live USB through the Universal USB Installer on Windows?

Yes, the ISO was mangled in transition from the server to your PC.

You can boot to the USB and run a consistency check but a bad ISO will make a bad install USB stick.

Why do you think there are pages of MD5 hashes as well as tguides how to check the data? Did you not think to check the data was good before using it, even if you have no knowledge of MD5 testing?

Torrents remove the need to test as the Torrent protocol has lots of data checks.

I greatly appreciate your help. However, I apologize for my lack of knowledge, all the tutorials I looked at were not from the Ubuntu website and never mentioned a data check. I've never done this before and I would really appreciate it if you weren't so condescending. I'm a beginner and am only trying to learn.

Also, it seems the Ubuntu hashes page is out of date. My MD5 sum is in fact correct for the 14.04.1 release which I found here: http://askubuntu.com/questions/503776/md5-hash-for-ubuntu-14-04-1-desktop-amd64-iso

Since my MD5 sum is correct, what steps should I take now to determine why my installer crashes upon attempting to install grub?
