Hey guys so I want to wipe my hard drive of an older Sony Vaio laptop.
I want to boot the program from a USB flash stick.
I have downloaded the latest version 2.2.8 and used the program Universal Extractor to burn the iso files to my FAT USB stick. When extracting, I get an error message saying, "7-Zip ISO CD-ROM image extractions cannot be logged." I ignored it and tried booting my laptop up. To no avail, my computer runs normally. I have also set boot devices correctly.
Please help, thank you in advance.
