    System reserved partition windows 8.1 ssd not optimized


    As the title says, windows 8.1 reserved partition will not optimize on SSD. Even if you try to run it manually. Have the latest firmware update for the SSD and Trim in enabled. Has anybody else come across this. Have googled it and there's no resolution that I could find. Image attached.

    There's absolutely no reason to optimize that part.

    In my personal opinion, it's best to just install Windows without a System Reserved partition. It's not absolutely essential and it's only real purpose is for BitLocker, so unless you plan to use BL then you dont really need it. Windows creates it by default during installation and stores the boot files there, but there is a way to bypass this and get the installer to put the boot files on the same partition as your C drive/system partition. Having a System Reserved partition also occupies an additional primary partition slot, which is usually unnecessary. I also encrypt my Windows (DiskCryptor), and not having a System Reserved partition is generally recommended for this, in part for security reasons.

    And another thing, I always install Windows in BIOS/legacy/MBR mode rather than UEFI/Secure Boot/GPT, because the latter has caused me nothing but headaches in the past. I see no real advantage in using UEFI/Secure Boot at this point in time.

    If you want to remove SR during install then just create a primary partition at the beginning of your drive and format it as NTFS. It's usually best to not have any other partitions on the drive at this point unless absolutely necessary, so go ahead and delete all partitions on the drive before formatting. Then open up a command (CMD) window using Left Shift + F10, type in "diskpart" (no quotes), and "list devices", and then "list volumes". Select the partition whose size matches your drive ("select volume [volume # here]) and then type "clean" (unless you have other partitions on the drive that you need, in which case "clean will *DELETE* them!), then "format fs=ntfs quick", then "active", then type "exit" twice. Click the Refresh button, select the partition you want to install to, and then you're set.

    I'm not sure if this or something similar will work for a UEFI install of Windows, and I dont know anything about optimizing an SSD since I've never used one. But I suspect that having only 1 system partition will help in this regard, just a shot in the dark. It's also possible to get rid of SR after you've installed, which will move the boot files to the C drive, Google for it.

    Hope this helped!
