I have 2 Hard Disks

- C:/ (System)

- D:/ (Storage)

I was trying to install Kali Linux using my USB, I downloaded the iso and burned it using unetbootin, I rebooted but it was not detecting the USB, I went to the BIOS settings, and changed my boot config from UEFI to Legacy, I saved the changes and rebooted, I was sent immediately to the Kali Linux GUI, tried to install it and I came to the step where it asked for a drive to install the GRUB on and it recommended to make it "Guided - use entire disk" because it did not detect any other OS probably because I changed the boot settings to Legacy, anyway I chose my D:/ drive because it had more space and the C:/ was used by Windows Already, after the installation process completed, it rebooted to a black screen with a blinking cursor on the top left.

I went back to the BIOS settings and changed the boot type from Legacy to UEFI and it booted to windows normally, but my D:/ drive is now missing!

Now I can't boot into Kali Linux, and when I boot to windows (D:/) HDD is missing


If The Linux Distribution got installed on that D:/ Disk then it probably uses GPT as partition-table and has the ext (probably ext3 or ext4) filesystem on it. Windows can't read those (Linux can read almost all Filesystems there are, and definitely every common one including the windows ones NTFS and FAT)

How to make Windows read that Filesystems. That is a different question. I can not give you a full explanation of (but it should be pretty easy. Like install one driver or programm and it works).

I found this Tool: Link

Ext2Read is an explorer like utility to explore ext2/ext3/ext4 files. It now supports LVM2 and EXT4 extents. It can be used to view and copy files and folders. It can recursively copy entire folders. It can also be used to view and copy disk and file.

I hope this was helpfull.

  • Thanks for your answer but is there's any way to revert this? And restore the filesystem as it was before without losing data? – Waftrue A. Sep 4 '16 at 5:20

    I don't know about your installation. But if you did a disk wide partition than the old partition containing the old filesystem got wiped. (Obviously) And I think this is the case becaaaaause: If you had made a separate partition for the os installation then the remaining windows one would still show you its filesystem (ntfs or fat) in the explorer. You could try some data recovery tools. That's all there is left sorry :/ But what the hell is Kali Linux dude.. as a beginner try something easy! Like, Ubuntu. I myself use Debian and I can barely use it! – Junaga Sep 4 '16 at 5:30
  • I'm using my windows normally now installed on my C:/ drive but as I mentioned D:/ is missing, and I can't boot to Linux after changing from UEFI to Legacy it shows a black screen with a blinking cursor on the top left. – Waftrue A. Sep 4 '16 at 5:34
  • as I mentioned: the Disk does not get shown because windows can't read the filesystem you need to install something to give windows the ability to. About the files that were there I am pretty sure you can save them. If you find the right recovery tool. The partition containing the filesystem(what contains all files) got reformatted I am sure it wasn't a complete reformat where everything gets overwritten by zeros. – Junaga Sep 4 '16 at 5:47
  • just the entries inside the partition table that mark where the partition starts and where it ends got rewritten. Then the space where the Linux files from the os installation got placed got overwritten. that is not a really big program Linux is usually never then a few gigs big. so you need to find a recovery tool for recovering overwritten windows partitions. – Junaga Sep 4 '16 at 5:47
