I have a Lenovo Thinkpad X220, which lacks a DVD drive.
I am wanting to install OpenSUSE on my laptop in UEFI mode, because it has an SSD, and I would rather use GPT than MBR on it (and my laptop will not boot a GPT hard drive unless it is in UEFI mode… I have tried workarounds, but I think it is a limitation of the firmware of the laptop itself).
I have not been able to boot the laptop in UEFI mode from the installation media. I have tried Unetbootin, using dd to copy the media to the drive, and formatting the drive as FAT32, marking it as bootble, and copying the files from the ISO to the USB drive (this has worked on other distros I have tried in the past like Arch Linux).
Does anyone have any tips?
I do not have an external DVD drive, otherwise I would try that.
