Me: "Ok, downloaded the (windows) iso, now I need to create a bootable usb"
* Pulls out 4Gb usb drive *
Father: "That iso won't fit on that one"
M: "Oh yeah right, do you have one for me"
F: "Sure"
* hands over 64Gb usb drive *
M: "thanks"
* Checks content *
* "Backups 15" directory and other old files *
"Guess I can use that"
* dds iso on usb drive *
dd: "done"
M: * Reboots *
Pc: "Nani the fuck is that supposed to be"
M: * searches online for solutions, tries out 2 different ones, one being provided by microsoft *
P: "lol no"
F: * comes in *
"Is it working?"
M: "Nah, windows a bitch"
F: "ok, can you copy me some files on the usb in the meantime?"
M: "Sure..."
{ How did he know that the drive is currently empty? }
* copies files onto stick *
F: * sees empty usb drive*
"Did you delete the contents on the usb?"
M: "Kinda, that happens when you create a bootable usb drive"
F: "..."
M: "Why do you ask, was the something important on the drive?"
F: "Idk, doesn't matter anyways now, since the contents are gone"

Btw, it still doesn't boot from the usb drive. Windows 10 iso is a bitch.
