Change OS Drive Letter
I've got a two hard drive laptop set up and I'd like the OS to be on my faster 256GB OCZ RD400 SSD but with a letter other than C: I don't care what letter, just not C.
My larger 1 TB drive, is what I'd like to label as C: without the operating system on it. I use DropBox with my colleagues and the CAD references look at the drive letter - so my xref files, data shortcuts, etc.c won't be found if my DropBox folder is on my D drive.
I've tried using Minipartition Toool Wizard and EasyBCD to copy the OS from one drive to another hoping it wouldn't always default to C: but it does. My laptop is set up for UEFI and GPT disks which is new to me and was quite confusing at first. I've tried using DiskPart to no luck - won't let me change the C letter. I even edited a file DOSDevices in REGEDIT - computer wouldn't boot after that...
I have not seen any way in Windows 10 to change the drive letter during set up, etc. It's always C. I even installed the OS on both drives and had a dual boot setup - but it always made the OS drive letter C and I don't want the OS on my 1 TB drive - it is noticeably slower.
Any thoughts are appreciated. Thanks. In summary, I'd like the OS with letter D: on my 256GB RD400 SSD and DropBox on my 1 TB HD with the letter C:.
