In and attempt to have a dual boot laptop


Ive been trying to get get the slackware install to recognize the D: drive on install.

After trying every scenerio online. I still come up short.

I was thinking of changing the physical location of the drive?

Out of the box (2018) it was setup in RAID config.

The BIOS shows the two drives as
First HDD none
Second HDD none
Third HDD IntelSSDlkji (180.G)
fourth HDD sd2000louol (2000.3G)

Was wondering if I could move the D: drive to the first or seconds spot?

And any other actions I would need to take?

Try using a Linux Live CD like systemrescuecd. Boot it, see if that detects it.
Also look at the output of "dmesg", see if that reports any errors, and the output of the command 'lsblk'.

I'm not too familiar with Slackware installer, but if there is a way to get to a command line interface WITHIN the installer to run commands, you could do this within the Slackware installer. Often with Linux installers you can get access to a shell.

dmesg will show you all the kernel messages. If you look through it, it will mention everything the kernel has detected in terms of hardware. It will indicate if its found the other hard drive or not, and should detect any RAID set up.

lsblk is another command which simply lists block devices.

It is a little unusual for Linux not to see the drive, I've never really come across that before.

It's also important to understand that Linux does NOT do drive letters, it does devices. C: and D: are windows constructs for PARTITIONS. First partition C:, Second D: and so on. D: could actually be on the SAME disk as C:

Also, if you have a second hard-drive, but it is NOT partitioned for Windows, it
won't come up as D: at all.

If you could let us know what 'lsblk' reports, that would help.

A drive will appear to be something like
/dev/sdd
with each partition
/dev/sdd1
/dev/sdd2
etc

The fact that the BIOS is finding it means that Linux SHOULD see it as well. Lets see what Linux actually reports first, and verify this isn't simply a case of it actually seeing it and you not recognising that it found it.

I ran dmesg yesterday, but have to figure how to pause it. Shift/up arrow doesnt do what it did in previous versions.
Will run lsblk today and see what the output is.

It's also important to understand that Linux does NOT do drive letters, it does devices. C: and D: are windows constructs for PARTITIONS. First partition C:, Second D: and so on. D: could actually be on the SAME disk as C:

Although it seems to have limited CLI i did try and mount /dev/sdb1 it just hung there and gave no error message

It's configured in WIndows as D: and disk1 where C: is disk0 which leads me to believe it's two seperate disks?

If you could let us know what 'lsblk' reports, that would help.

After chores this morning I'll try the 'lsblk' and 'dmesg' after i find the switch to pause it

Thank You for your insight and time to help

use lsblk...

(sorry for the dump. better to have a huge example)

$ lsblk

ÃÄnvme0n1p2 259:2 0 99M 0 part
ÃÄnvme0n1p3 259:3 0 16M 0 part

ÀÄnvme0n1p5 259:5 0 666M 0 part
nvme1n1 259:6 0 465.8G 0 disk
ÃÄnvme1n1p1 259:7 0 16M 0 part
ÀÄnvme1n1p2 259:8 0 465.7G 0 part /mnt/ntfs-d

you're going to want to be VERY CAREFUL you fully understand which of these drives is which. for example, note that linux can see and i have mounted my two nvme ntfs drives for C: and D: on the windows side. you can see all the "junk" partitions on nvme0n1 that i've just left, as well as the primary partition. you can see sdd has my main linux partitions, including an EFI one for booting, a swap drive and the main linux partition (sdd3) and the separate drive for /home (sdc1)

so now you kind of have an idea what sort of things you're looking for, imagine you have a "storage-d" drive like me that you want to nuke for linux, which is under "sde"

$ cfdisk /dev/sde

i'm kind of suspecting cfdisk is just loading the first drive it sees, and cfdisk is *not* an all-the-drives-at-one-time maintenance tool, so you're thinking it isn't finding your drive. you do your work on one and then
save/close it out and then maybe do the next.

Not sure what that even means.

If he's referring to a specific hard drive he has, I imagined this might mean plugging it into a different SATA port or something.

That's exactly what I was thinking. but would rather not if I don't have to.

I never thought of that. I will try that

*SOLVED*

Result, cfdisk is not my friend.
Partitioned the D: drive in windows and used fdisk during install.

Thank you everyone for helping me figure this out

When I saw the drive visible with lsblk, it dawned on me to just try and force the issue with fdisk.

Now LILO is my only issue, but am able to logon to slackware with the install media. USB stick. And Ill probably just leave it like it is, and only log into widows if I have to.

Thanks again, everyone.

That is *exactly* what was happening. so i partitioned the drive in windows and use *fdisk* to set the labels of the partitions.

Thank You

Sorry, I am just seeing this. cfdisk was never my friend, either, but
linux fdisk usually works just fine. I would suggest always using it, over cfdisk, whenever you can.

I generally use fdisk unless I'm dealing with huge disks that require GPT partitioning, then I use something like parted. fdisk never used to handle GPT and I'm sure it does now, I'm just used to using something else.

I have also used parted without issues. IIRC, it was also for something
that fdisk (at the time) could not do.

Another bonus is that if you wanted more than 4 partitions with fdisk, you'd have to have a have an extended partition. I think this is more of a MBR thing. Using GPT you don't have to go through that silliness.

Of course, you can get away with not creating a partition at all and
using the entire disk as LVM :)
