Ubuntu 17.04 slow boot on SSD with dual boot
Solution 1:
I could find a fix that a Reddit user posted, it was actually a bug:
In Ubuntu 17.04, there is a bug in the installer when using home folder encryption - a swap partition is referenced but 17.04 now uses a swap file.
Open /etc/crypttab in a text editor and change the following:
cryptswap1 UID=XXXXXXXX
to this:
cryptswap1 /swapfile
Now my Ubuntu boots in like 6 seconds :-)
