Hey guys, So I'm trying to re-install windows on my laptop via usb (it has no cd drive) and when I try to boot the usb from the bios, I get a "boot mgr missing press ctrl, atl, del" message. When I only had my original hdd installed, i could access it fine, but later on I had someone install an ssd for me so the os is on the ssd now. From what I read, is it true that the installed ssd is preventing me from booting up the usb? Any ideas on what I can do?
Perhaps I misunderstand the OP, but no ssd/hdd will prevent you booting from usb. Have you booted from the same usb previously? Check the bios settings and do you know for certain the usb is bootable? Make and model of the laptop?
This^^^ The USB drive has to be bootable, in the boot order sequence and in this case I'd make it dead first.
Check your optical drives, USB ports, and floppy drives for media. Often times, the BOOTMGR is Missing error will appear if your PC is trying to boot to a non-bootable disc, external drive, or floppy disk.
I would re-format the USB drive via command promt and load a new set of files onto it. Run Command Prompt as admin Load your OS files Boot into the BIOS and make sure you boot from the USB and install your OS.
