E2B: Add Desinfect 2015 with updates

I have made a new mnu file for Desinfect 2015 with persistent updates.

Making the .mnu was simple, but I just couldn't get the updates to work. I could copy them from the 'master' flash drive partition to the ext2 filesystem on the E2B drive, but when I booted to Desinfect 2015 from the Easy2Boot drive, Desinfect always complained that the signatures were outdated and refused to use them or update them (updates went to RAM not the USB drive)!

It turned out that I was not copying ALL of the files because I was using the linux command:

sudo cp -purv /media/desinfect/desinfSIGS/* ss

what I should have used was

sudo cp -purv /media/desinfect/desinfSIGS/. ss

spot the difference!!!  linux is sooooo user friendly (not)!

The important file that was not copied was the empty file  .desinfect2015, which explains why Desinfect 2015 thought the signatures folder was not the correct one!

The amended instructions for 2014 and 2015 are in the updated old blog post here.

Access ext2/3/4 partitions from Windows

I actually installed ext2fsd on my Win8.1 64-bit Windows system so that I could look at the contents of the Desinfect 2015 'master' flash drive more easily. Because, I was using a Removable flash drive, I had to use RMPrepUSB - Ctrl-O to move the type 83 ext4 signatures partition (#3) to the first position in the partition table. Once that was done, the ext4 signatures partition was available to me in Windows Explorer and I then noticed the .desinfect2015 hidden file!  I could have used ls -a under Linux to see the hidden files also.

P.S. Any donations to Easy2Boot are welcome ;-)
