From above link

Hello, I was installing debian 9 on an old thinkpad E430 but I ran into some problems at the selecting disk stage. it would not detect the 100gb ext4 partition I wanted to install onto, but instead only detected the complete 320gb disk in its entirety. I wanted to have it dual booted with the already installed windows 7 and have the debian partition be encrypted with LVM. I partitioned the disk with minitool. I also know that the iso image I am using is legitimate because I checksum and gpg verified it. I have tried searching for the problem online and posted it on other forums but I couldn't find any help. If I could have some help figuring this out it would be much appreciated

Code:

    ~ # fdisk -l
    Disk /dev/sda: 298.1GiB, 320072933376 bytes, 625142448 sectors
    Units: sectors of 1 * 512 = 512 bytes
    Sector size (logical/physical): 512 bytes / 512 bytes
    I/O size (minimum/optimal): 512 bytes / 512 bytes
    Disklabel type: dos
    Disk identifier: 0x6364f2eb

    Device        Boot     Start             End        Sectors   Size    Id  Type
    /dev/sda1  *            2048     1026047       1024000  500M   7   HPFS/NTFS/exFAT
    /dev/sda2           1026048 420339711   419313664  200G   7   HPFS/NTFS/exFAT

I posted on the debian forums a couple days ago but my problem went unsolved and I stopped receiving suggestions so I am posting here. I am sorry I would attempt to figure this out myself but I have minimum experience with linux so not sure where to really begin and I am a bit short on time so I figured I would post here. As always, any help received would be much appreciated.

Hi & Welcome to LQ.

In order to install Debian alongside of your Windows os you will first have to shrink your Windows partition. Go into disk management to do that. Shrinking Windows to 160GB should be good.

Once your Windows partition has been resized you will have 'free space' during your Debian installation to install to.

You will need to make a 1 GB linux-swap partition from that free space. Than you can use the remanining free space to make a ext 4 file system for your Debian install.

Once Debian is installed IF Windows doesn't show up in your Grub Menu just open the terminal in Debian and run this as root:

Code:

sudo update-grub

Good luck with your install-

I am unfamiliar with minitool but from the output of the fdisk command there isn't a 100GB linux partition. If using LVM and encryption you will need two partitions one for /boot and the LVM that contains swap and whatever other partitions desired of which the minimum a /(root) partition.

If you pick guided partitioning using free space the installer will walk you through the steps or use manually partitioning if you feel comfortable with doing it yourself. If you use another partitioning tool you will need to select manual partitioning. You will need to manually select the desired partition, mount point and filesystem type.

Okay, but how do I get the installer to detect the partition?

michaelk · 08-28-2018, 12:58 PM

From the information posted there isn't evidence that a 100GB partition was created successfully.

A fdisk, gparted screen shot from any linux live CD or Windows partition manager should show if it was actually created. Regardless the debian installer will create partitions using available free space.

Alright, that is weird though because my windows partition detects it with the help of ext4 software.

Ztcoracat · 08-28-2018, 03:36 PM

Did you shrink your Windows partition to make room for your Linux installation?

sorry but this is not true.
you received quite a few suggestions, but stopped reacting to them.
at first glance i can see that you never even followed up on the request made in the first reply.
all you managed was to provide the output of "fdisk -l", and silence after that - from you, not the others.
many follow-up questions went unanswered.

and also here i can see that you are not really working on the problem yourself.
asking rather monosyllabistic questions instead of providing further information.

Getting back to the issue.....

"From the information posted there isn't evidence that a 100GB partition was created successfully. "

I echo this observation.
