      If you have a USB drive connected to your computer, Fedora Media Writer will display that as the target device to create a bootable image. ​ Note:​ Fedora Media Writer destroys all data on the USB stick while creating a Live USB media. We recommend you back up the contents of your USB drive beforehand.
    4.  Select ‘Write To Disk’ to initiate the Live USB creation process. The ‘Write Custom Image’ window should identify the connected USB drive.

FREQUENTLY ASKED QUESTIONS

Hardware and Bootable Media

Why does it take a very long time to download the Remote Exam Live USB image?
The Remote Exam Live USB image is approximately 2 GB in size. Download speeds can vary depending on a variety of factors such as the available bandwidth and download speed of your internet connection at the time of downloading, number of users connected to the same router, distance from your wifi router, hardware specifications etc.

Fedora Media Writer throws errors while creating a Live USB on Windows 10
There are a few errors seen occasionally when Fedora Media Writer is used to create a Live USB from an iso file in Windows 10. Some of the screenshots given below.

  1. The Remote Exam image size is at the borderline of 4GB and hence using an old 4GB thumb drive will cause the above error as the actual size of the image exceeds 4000 Megabytes. Use a drive that is 8 GB or larger in size.
  2. Fedora Media Writer saves the ISO to your USB and then reads it back to verify that it gets the same data back as it wrote. If the read does not match the write, FMW will show an error saying ‘Your Disk is Probably Damaged’. This is a very stark message which actually means “Warning – there are inconsistencies between what was written and what was read back”. There are many possible reasons why the read might not match the write and it doesn’t always necessarily mean that the write failed or that the USB will not work. You can ignore this message on an otherwise known good USB and continue using the same.

Click on ‘Cancel’ to exit Fedora Media Writer, reboot your system and try to boot from the USB drive. If it boots successfully to the Remote Exam image, the USB drive and the image on it is fine and can be used for your exam.

  1. Clicking on the Retry button and re-attempting the write process may fix the error
  2. The above error may also appear if there is an existing Live USB in the disk already. The presence of a Live USB will be detected by FMW and a ‘Restore’ option will be available to format the drive. Click on Restore, finish the format process and reattempt the process of creating a Live USB.

After the exam, how do I reformat my USB drive?
Using Fedora Media Writer: Connect the USB drive to your computer and start Fedora Media Writer. ​You will see a prompt to restore the USB drive to “Factory Settings”: Follow the instructions to restore your USB drive to the Factory Settings

**Note to Windows Users: “Factory Settings” would most likely imply that your USB drive is formatted in the FAT32 file system. FAT32 does not allow transfer of files larger than 4GB and hence most Windows users prefer NTFS.
exFAT handles larger files and is Windows and Mac OS compatible. Hence, you will need to use an additional level of formatting using the Windows format utility.

Can I use a wireless internet connection?
Wifi is not advised. Wherever possible, use a wired internet connection for stability and compatibility. Wifi speeds can vary based on a variety of factors which may have an impact on your exam. The Remote Exam Live USB may not detect all wireless network adapters. If the wifi adapter of your computer is not detected by the Remote Exam Live USB image, then wired internet will be the only option.

How many free USB ports should be available for use during the exam?
You should ideally have a minimum of two USB ports available in a laptop for a bootable USB drive and an external web camera. In the case of a desktop computer, the requirement would be four ports for the following devices: One external webcam, USB drive, keyboard and mouse.

I am unable to download the Remote Exam Live USB image
Your computer and the network you are connecting from must have the necessary privileges and permissions to download files from a third party source. The operating system used must have administrative (Windows) or root/sudo privilege (Linux/Mac). Firewalls and Security restrictions on your network setup might block such downloads. Try a personal computer and/or home network to perform these tasks.

Can I boot to the exam environment using a virtual machine rather than a USB drive?
No. The Remote Exam image must be loaded on a USB drive. Booting off a Virtual Machine is not allowed.

Can I create a bootable live USB by keeping my existing data in the same USB drive?
No. The process of live USB creation will wipe out any existing data and reformat your USB drive as needed.

Is a desktop computer allowed?
Yes

Is an iMac allowed?
Compatibility cannot be guaranteed. If your pre-exam test by booting in to the Remote Exam Live USB works fine, then you can proceed. A few things to note:

  • iMacs come with wireless keyboard and mouse. Wireless devices may not work.
  • Detection and stable performance of wifi internet is NOT guaranteed.
  • Using a wired keyboard and mouse and a wired internet on an iMac should work fine subject to successful pre-exam testing.
  • One external webcam with at least 1m cable and 90 degree field of view or more is required. The webcam must be focusable from 10 cm to 2 m.
