Good Day ALL, I'm a newbie to Tom's Hardware, but, i've read some pretty good discussions over the Net. Well, my scenario, is, I purchased an HP 590-p0054 off EBay 2 weeks ago. Of course I researched its specs on the HP Product Specifications page first. Everything seemed to be in order, according to the sellers description. I saw that it originally came with a128gb NVME ssd (for 1 M2 slot), and another M.2 slot (for WLAN). After unboxing, and connecting the pc up, I noticed the C drive was nearly full. So, I decided to get a larger capacity M.2 NVME to replace it. Of course I got an enclosure so I could clone the disk. Downloaded Macrium Reflect, initialized the new disk in Disk Management and proceeded to clone the drive in the pc. Process completed successfully. Here's the thing, upon removing the preinstalled M.2, I saw that it was a SATA M.2 drive. Needless to say, I installed the disk I cloned and WALLAH, it wouldn't boot!!! it did give me a BLUE Screen telling me......OOPs something went wrong! Alson indicated incompatible hardware. So, there I am wondering why this is happening. I've have had no problems in the past cloning drives and using them in my pcs.......and they were older than this one. I should mention, that although the specs say the 590-p0054 comes with Win 10 installed, the seller must have let it upgrade to Win 11, that's what showed up when I powered it up. Honestly, I'm a BIG fan of Win 10, even my wife likes it ( she's a REAL pc novice). So, I researched reverting back to Win 10. And found I could do it with the HP Cloud Recovery Tool. Enter your serial number, and it tells you if can revert. Well, mine could be reverted. So, I placed the tool on a USB drive(required) and ran it. It worked, I was back to Win 10 (of course when the PC was released). After a day or two of updating, it is at thr current 22H2 version. Enough of that. All I want know, is does this Lincs MB accept M.2 SATA or NVME? Are they interchangeable. Id don't know the technical aspects of these drives and what slots they can or cannot be used in. I read what comes with the machine and try to match what I've read. Is ther anyone with more tech savvy than I, that, can give me some guidance on how rectify this issue I seem to have brought on myself?? OH, sorry for the long scenario. Just for clarity, I'll supply the link to this pc. thanks. https://support.hp.com/us-en/document/c06124759
