I'm trying to use a live USB to dual-boot Ubuntu 13.10 and Windows 8.1. I made the disk with pendrivelinux (per instructions on the Ubuntu website).
It all completed successfully, I checked the md5sum of the .iso file and it was correct.
When I restarted my computer and booted off the flash drive, I ran "Check disk for defects" and it ran properly, but returned that my disk had 2 defects. However, it wouldn't tell me what the defects were. It seemed to be checking files on the USB device itself.
But from Googling the problem some people say it checks the USB and others say it's checking the computer's HDD. I re-created the USB drive and had the same error.
I'm wondering what this actually means, and if it's safe to install Ubuntu. I'm writing this on the Ubuntu desktop (without install) and it seems to be working fine.
How can I solve this ?
