Boot installer from USB
Hello everyone,
I have done a mess with my partitions, bootloader etc...
I have recently installed Debian. However, in order to do that, I have removed practically all the other partitions (currently there is a 500mb FAT partition, 17GB for swap and the rest is the main partition).
I wanted to return to Windows so I burned the iso downloaded from the Dell webpage into an USB drive but it doesn't show in the boot list (pressing F12). I tried different combinations of settings like secure boot disable or SATA as AHCI. I have also restored the settings as default but nothing changed.
I tried to add a UEFI boot entry for the USB but I couldn't find /boot/efi/bootx64.efi which could be the problem. But I don't know how to restore everything.
I hope that you can come up with some ideas because I searched everywhere on the internet and I couldn't solve the problem...

Hi,
it seems that many questions posted to this forum do not receive any answer.
Out of desperation, I will nevertheless make an attempt here.
I am in the same situation as GiulioZh with my new XPS 13. I can't boot from
USB (though I was able a few time before reformatting by HDD). I don't understand
why touching HDD had consequences on booting from USB...
I tried to boot a Debian 9.2.1 image on a USB 3.0 key and I checked the key is
bootable with another computer. With the XPS 13, I tried different
combinations (UEFI, secure boot disabled, AHCI, enable legacy and tried USB
mass storage from Legacy boot settings). None of them worked: the system
answer no bootable OS is found, or it falls back to diagnosis page.
I am stuck and would really appreciate some help! Hopefully GiulioZh sorted this
out and can provide some information.
Thanks,
Eric

Hey,
Well I have managed to solve the problem. The problem wasn't with the BIOS or EFI but in how I burned the iso.
In fact, previously I just burned the iso with the command "dd" or through disk. So what I did is get a windows pc, download the iso and burn it with rufus, you can do the same with "unetbootin" in linux (however I couldn't install it on debian, while it worked in ubuntu".
The configuration was just random and the USB showed in the UEFI list and not Legacy,
