Background (skip to QUERY if you wish): While in Florida recently, my wife and I spotted a nice 11.6" Dell Inspiron for $300 US. The design is "old", with 500GB spinning disk, 4 GB Ram, quad core processor that isn't terribly powerful. However, it is a size Mary likes for travel, and enough disk for lots of family photos and videos. (Her previous Asus EEE 1225B was similar, but heavier, and suffered an unfortunate collision with a tile floor that has made it only partly functional.) We've tried Android tablet, but the key layout on Android -- and we've looked around at several -- makes doing email and stuff awkward. And they don't store much. It has Windows 10 and works reasonably well with this. We'd like to keep the Win10 in dual boot. Sometimes useful to test things. For safety, using the Windows 10 recovery disk tool (Control Panel / System & Security > Security & Maintenance > Recovery) created a recovery USB on a 16 GB Lexar flash key. Also downloaded Clonezilla clonezilla-live-20170905-zesty-amd64.iso and used mintstick tool to install on a USB key (only uses about 275 MB). This is in the alternate repository for Clonezilla and allows UEFI booting. The regular "stable" choice did not boot. Made a whole disk image using this and put it on an external USB drive from the Dell.

Some forum comments say this can be risky. Does anyone have recommendations or experience? - Some net comments suggest using Windows tool to do this. It appears that the MiniTool Partition Wizard (https://www.partitionwizard.com) can do this. - In linux there appears to be fixparts from https://sourceforge.net/projects/gptfdisk/files/gptfdisk/1.0.1/fixparts-binaries/ Other choices? My current plan is - to convert the 465G particion with the free version of Partition Wizard - test Win10 boots - use partimg from liveUSB to image that converted partition - shrink the Win10 partition - test booting again - use partimg again to save (replace previous save) - install Linux (Mint 18.3 Sylvia is what Mary is used to) to the freed-up space. Comments and suggestions welcome. Best, JN
