Can't install Kali Linux from USB, fails to find CD-ROM drive
Solution 1:
You could resolve the error by repeating the steps :
Run the installer.
Open a shell (ALT + F2).
Create the directory cdrom directly on the root of the file system:
mkdir /cdrom
Note : If you got problems making the directory /cdrom, disable the CD-rom player in BIOS or disconnect the cable
Mount the USB as if it is a CD-ROM:
mount -t vfat /dev/sdb1 /cdrom
Where sdb1 is your USB device.
You could carry on installation now
After executing mount -t vfat /dev/sdb1 /cdrom, cd into the /cdrom directory and do an ls to see if the files are there. Then press ALT-F1 to go back, continue and re-select "detect CDROM"
Source :ubuntu and debian
Another layman solution was :
when the Window shows CDROM couldn't be mounted ,
Unplug your USB from system and re insert it
wait for mount/ detection (usb LED glow)
Hit Continue
You could do what I did. Hit escape, type install, hit enter, skip CD drive.
Solution 2:
If you use Rufus (v 2.x) to burn the ISO to USB drive, make sure the option is "DD Image" in "Create a bootable disk using". Not sure if Unetbootin offers the same option. If image is copied using this method, you don't need to go to terminal and manually mount it.
With Rufus (v 3.x), you can not explicitly choose DD mode. IF the ISO is hybrid or has DD mode, Rufus will prompt you to choose ISO or DD mode AFTER clicking start button.
Solution 3:
I tried all the answers here and more google results, but none worked. I eventually figured it out, the issue is the file format is not vfat, but iso9660.
When you get the CDROM not found error follow these steps:
Enter a shell (CTRL+Alt+F2)
Note: Kali told me to press (Alt+F2), but this didn't work
Get a list of devices with blkid:
~ # blkid
/dev/sdc1: UUID="2018-04-12-12-04-16-00" LABEL="Kali Live" TYPE="iso9660" PARTUUID="81c5e086-01"
Note: I have shortened my list to the relevant row. Also you can see the storage type is iso9660, not vfat
Mount the Kali CD with the mount command:
~ # mount -t iso9660 /dev/sdc1 /cdrom
Check the contents of /cdrom are as expected:
~ # ls /cdrom
autorun.inf efi g2ldr.mbr md5sum.txt win32-loader.ini
boot efi.img install pool
debian firmware isolinux setup.exe
dists g2ldr live tools
Switch back to the installer (CTRL+Alt+F5)
Note: Kali told me to press (Alt+F1), but this didn't work. I tried F1 through to F5 until I found the correct combination
From the menu tell it to mount the CDROM, if asked choose /dev/sdc1 and /cdrom. I know we have already mounted the drive, but for some reason this step didn't work previously, but worked fine after following the previous steps.
The install will now continue as normal.
Solution 4:
checked the issue myself right now: it's a WAY MORE simple - use "Graphical install". It seems to rise additional hw-related services and it works just fine! Also - if you're using 2 flash drives - plug OFF the drive you're about to install it to, boot it in GUI - and then plug the target drive.
Solution 5:
I have tried every single answer but none of them worked. After some more searching online I found an answer that worked for me.
It is fairly simple but just download Win32 Disk Imager. Click on the folder icon and change the filter to all files or . Then select your .ISO file, select your device and click on write.
After doing this I inserted my USB (3.0) into a USB 2.0 port on my computer. When I booted to my USB it worked instantly.
