Ubuntu Server Installation

Wipe off the USB drive

Insert the USB drive.
Open Terminal.
Find the location of the USB drive:
- Type in the following command to list all the drives. This should show a listing of the different drives.
```
diskutil list
```
- Find your USB drive in the list (it will be something like /dev/diskX (external, physical) where X is the number assigned to your USB drive. Look at the size of the drive to verify that it is the correct drive.
Before erasing, you may need to unmount the drive. Replace X with the correct disk number (e.g., /dev/disk2).
```
diskutil unmountDisk /dev/diskX
```
Erase the drive:
- Use the following command to completely erase the USB drive and remove all partitions. This will erase everything, so be sure you have selected the correct disk.
```
sudo diskutil eraseDisk FAT32 NEWNAME MBRFormat /dev/diskX
```
- Replace NEWNAME with the name you want to assign to the USB drive, and replace diskX with the correct disk number. You can also change the file system type (FAT32, APFS, etc.) and partition scheme (MBRFormat for BIOS systems or GPT for UEFI systems) if needed.
- For example,
```
sudo diskutil eraseDisk FAT32 UBUNTU_SERV MBRFormat /dev/disk2
```
