So, I’ve had this computer for a long time, I’ve kept it up to date, all fresh drivers and what not, hardware’s mostly up to date, and I have windows 10. Just now, I installed a SansDisk SSD to it, turned on my computer, formatted it just fine, then I turned my PC off for little less than an hour, and I come back, and now I have a BOOTMGR missing error. I’ve gone into BIOS, changed my load order around, I’ve gone into my computer, unplugged the SSD and tried it, unplugged my hard drive and tried it, and I have no clue what’s going on. Help!!
