i tried to install win7 to my friends not new laptop acer with intel celeron N****(with win11, someone i gues joked and installed on his laptop win11) he asked me to install on his laptop win7 cuz win11 on celeron N**** is lagging. in the beginning i tried to install win10 to check if it can run win10 without lags of system. when i tried to install win10 i wasnt able to format drives on laptop. then i go to BIOS and turned off checking licenzed drivers to install cracked win10. then i run installation and formatted all drives. next i decided to install win7 cuz i guessed win7 will run better then win10 on celeron N****. then i made USB flash drive with win7 and tried to install it but laptops wont let me install it and gives me black screen (with i first think artifacts like when graphic card is damaged but then i realized they are very small letters and number) after acers logo. now the only thing i can is to press f12 when laptop is turnings on and choose what i want to boot 1.laptops HDD 2. ATAP I CDROM 3.network boot 4.USB flsh drive. ( nothing works of this given options after choosing all of them it backs to "artifact black csreen)
