I recently fixed my friends computer, and installed Ubuntu 13.10 on to it.
To do this, I used my flash-drive (he had no disc reader). However, now I want to undo what I did to the flash drive.

I created the drive on Mac OSX following the official websites instructions to create the flash drive. I have already formatted the drive in windows, but now it's only 2.7 MB big.

How can I un-Ubuntu the drive? I'd really like to not have to buy a new one.

EDIT: Instructions on how to do this on EITHER OS (Mac or Windows) are good. I don't have access to the Ubuntu machine any longer. (sadface again)

    How did you install Ubuntu on it? And how did you format it in Windows? Also, read the help center to learn why you aren't allowed to add "Hello". We aren't a forum ;)

  • I followed the instructions on the official website for creating a bootable USB. I then installed Ubuntu 13.10 off of the drive (by selecting it from boot-priorities in the BIOS) and ran the install like normal. I then plugged the drive into my Windows machine (I used my mac to create the drive because I was away from my Windows machine when I created it). I right clicked the drive in the list of devices, hit "Format..." and selected a format of FAT32. Jan 31, 2014 at 1:56
  • @Seth Thank you for making the use of the word "Hello" on the site clear to me. I guess that's useful to know! Jan 31, 2014 at 1:57
  • What was the size of the driver before you reformatted it?

  • Anywhere from 4-8 gigabytes, I believe. Not very sure about this. I've just had it lying around for doing exactly this. Jan 31, 2014 at 2:15

In Windows:

Control Panel -> Administrative Tools -> Computer Management -> Disk Management

Delete all the partitions on your flashdrive one-by-one by right-clicking on each partition and selecting Delete Volume. Then create a single partition on the free space and format it as NTFS or FAT32.

  • Thank you for the reply! I had my Mac in front of me, so I used basically the same process to undo what I have done on from my Mac. Appears to be working thus far. If all succeeds, I will for-sure give you that all important green check. Thank you so much! Jan 31, 2014 at 2:37
  • Working perfectly! Thank you so much for your help! Jan 31, 2014 at 3:09
