UEFI BIOS won't recognize USB

-1

I recently tried to install Kali Linux from a live USB. This didn't go too well. I used Rufus to create a live cd on my USB from the Kali Linux ISO. Then I rebooted, and went into BIOS to boot from USB. It didn't show up. I booted into windows, and now I cant look at my flash drive. If I try formatting it with the default windows formatter, it says I'll only have 2.7 gigs on it. This is an 8gb hard drive! Should I try formatting it with Rufus, and trying again, but using the GPT partition? I read this post

but I'm confused about which partition I should use for my BIOS to recognize it so it would work with UEFI. GPT? MBR? Not sure. Help would be appreciated.

You can't use MBR if you have a UEFI bios, you need to make sure, the disk has the EFI drivers on it. – Ramhound – 2015-08-02T17:36:52.057

@Ramhound, I'm not quite sure what you mean by EFI drivers, I'm quite new to this – Grant Parajuli – 2015-08-02T17:39:36.367

In order for a disk to boot in UEFI mode it must contain the drivers to do so. If it isn't working, that tells me, the those drivers are not on the disk. – Ramhound – 2015-08-02T17:42:36.773

If the flash drive is seen in the Administrative Tools -> Disk MAnagement, delete whatever partition is created on it and first create & format a FAT32 partition all along. Using latest Rufus try selecting GPT Partition Scheme for UEFI as partition scheme option when creating bootable USB from ISO. Keep File System as FAT32 and try again.. – patkim – 2015-08-02T18:50:59.650

finally fixed it, all I had to do was go into Rufus and create the same thing with a GPT partition. thanks everyone for trying to help – Grant Parajuli – 2015-08-02T20:16:03.287

1Extra drivers are not necessary to boot from a flash drive in EFI mode. Drivers may be required by certain boot programs (such as rEFInd) to read non-FAT filesystems, and they're built into other boot loaders (such as the Windows boot loader and GRUB). In other words, drivers are a red herring for Grant's problem. Also, most EFIs will happily boot from either GPT or MBR USB drives; but some do have problems with the latter, so GPT is the safer partition table type. – Rod Smith – 2015-08-02T20:16:48.537

Ah ok @MichaelKjörling thank you for telling me, I thought it wouldn't be something like the (SOLVED) – Grant Parajuli – 2015-08-02T20:29:20.977

Solved by going into rufus, and then reformatting the drive with an ISO to create a new live USB with GPT rather than mbr. This fixed the problem and I can now succesfully boot into Ubuntu.
