Hi Henk,
Cool! Glad to hear that.
That's another project I intend to mess around with on my W10 test machine. Right now I'm fighting with getting all my machines on the
AU v1607 b14393.187. I did however have a post a month or 2 ago, about doing a
dual-boot on my little Acer AspireOne netbook with
W10 (pre-AU v1511) and Ubuntu. It turned out whatever I did I couldn't get the newest Ubuntu version, v16.04LTS to dual-boot with my W10 on the Acer netbook. I wiped the drive clean, tested it and all was fine. It just refused to go.
I decided to fall back to the 30-yard line and punt the football--I reinstalled the Ubuntu partition after another W10 reinstall and ran with the Ubuntu 14.04LTS from 2014 and it worked!!
I haven't messed around with that as I have been busy painting the outside of my house before the snow gets here, and handling the crush of folks with scrambled computers (W7, W8x, & W10) that I've had for the last 2 months.
Both here and my Clients computers too.
I was going to try it again with the W10 AU v1607 and Ubuntu v16.04LTS (new version) on my big Sony Laptop, but I have a small 128GB SSD in there so I don't have enough room on that drive to add the partition needed. But, I got another new internal HDD in the mail a bit ago for my W10 test machine, so maybe I'll give it a go there. I think it's a 320GB HDD, so I should have plenty of space to do a test install.
If you've been reading the threads lately, we've have a few other people try the dual-boot with W10 and various versions of Linux including Arch and Mint, and they've had lots of problems too. I'll post back if I have any success there. We could start an entire subforum just devoted to all the work needed to fix people attempting dual-boot and multi-boot OS issues.
Thanks for posting back your solution--that should help some people too.
Talk to you soon,
BBJ
