Lenovo X270 issue when attempting dual install

techmod · 2018-01-19 08:56:59

Hi everybody,

so I have the following issue:

I am trying to attempt a dualboot install of Arch and w10 to my machine. Secure boot is off and everything should be set properly. When I issue

 lsblk

I get to see the drive as nvme0n1 with all of its partitions (so ncvme0n1pX) on which windows is installed.

I have half of the drive left free for an arch install. So actually I expect to see another drive as nvme0n2. But that isn't the case. Instead I don't see anything at all besides the live stick and windows. So what am I missing here?

EDIT: Maybe I should add the fact, that if I leave the arch partition unallocated it doesn't show up, but if allocate an unformatted partition to it it will show up as a fifth partition.

Thanks for your time!

Why do you expect to see another drive? You expect to see another partition which is the pX part and what you are seeing. nvme0n2 would be a seperate namespace, which you could set up if need by with e.g. https://aur.archlinux.org/packages/nvme-cli/ or similar (however this is quite unlikely to be relevant for a simple dual boot unless you are really interested in creating separate namespaces).

But where is the difference to splitting other ssd's? They always show up as sdX and sdY on the same drive. So actually I should split the second partition as needed and install as usual then.

nvmeXnYpZ

X = drive Y = namespace Z = partition

I'd assume that what you are refering to might've been hybrid hdds which technically are two drives? I don't think this is as generally applicable as you think it is, or you are mistaking separate drives for the same drive. i.e. on my laptop there's a 250GB SSD and a 1000GB HDD which naturally show up as /dev/sda and /dev/sdb respectively but they are clearly different drives.

With which system/drive have you had that experience that leads you to that conclusion?

No I don't mean the hybrid drives. For clarification:

I have a one SanDisk ssd built into another laptop. When I split the drive into two partitions, I see /dev/sda and /dev/sdb. But I don't see this on the nvme drive.

Just in case I am getting something totally quirked up here I will recheck later. But my memory tells me the above. When issuing the lsblk command the partitions show up as two different "devices'". Maybe I am wrong, but I will have to check first.

I am installing now as I think it should work. I'll give you a heads up in a few.

Thanks for your help so far.

That shouldn't be, the schema on normal drives is sdXY

X = drive, Y = partition , e.g. sda1, sda2, sdb1 and so forth. Bear in mind, that if you refer to the output during install (or whenever you have a usb storage plugged in), that your live usb will be one of those two, so that's what you might've been seeing.

Or of course when you are talking about "splitting" you are refering to utilizing some volume manager like LVM and/or RAID or similar which can lead to such a setup.

It might well be that there's some other magic I'm not aware of, but that's how it usually goes.

Hi again,

sorry for the delay. So my memory was trolling me. However, I have found a temporary solution as seen above. But systemdboot doesn't recognize the windows efi partition.
