On my laptop, I have installed Windows 7 to an SSD that was brand new. When I start the system normally, I get an error that there is nothing to boot. However, through one time boot, I can select an option that has only shown up since the installation, UEFI Windows boot manager, which starts Windows normally. This option does not show up on other devices' one time boot and I cannot use the drive. Another thing to note is that the drive has not been recognized as one since the installation. Is there a way to fix this without a drive format? If not that's still fine, just preference.
