Your XPS 13 use BitLocker Encryption system for win 10 with TPM (Trusted Platform module). That's why you can't shrink your partition. I have had the same problem and this is my solution: 1. Turn off Bitlocker system by going to SETTING => SYSTEM => ABOUT => DEVICE ENCRYPTION => TURN OFF (you need to wait some minutes for ending process). 2. Turn on RUN window (window button + R) => type 'msconfig' => go to 'SERVICE' tab => unstick 'BitLocker Drive Encryption Service' => Restart your computer. 3. Then shrink partition normally in your computer. If the size is still small, you can use another tool like 'Mini Partition Wizard' (this tool is free) to resize your drive (you can't use this tool if the bitlocker system is turning on). 4. When everything is done, return on the BitLocker Encryption system and stick again in check box of 'BitLocker Drive Encryption Service'. 5. Restart your computer. Good luck!
I have a hard time to install double boot on my Dell XPS 13 (9360, late 2016), namely I can’t shrink partition (size of available shrink space is too small, 115MB on my 256GB SSD). Things I tried, did not help:- Switched SATA operation from RAID on to AHCI mode- Disabled Secure Boot- Disabled pagefile- Disabled hibernation file- Disabled system restore- Disabled writing debugging information- Cleaned up disk- Defragmented (3 different tools) 1) Am I missing something? What else can I try to shrink windows partition? 2) Is it safe to wipe out all the partitions (including windows, restore, etc) and install Ubuntu? What are the downsides? Can I still update BIOS? UPD: I don't care about data loss, because it's a new laptop (does not have any of my data yet).
