Hello to all of you
I use a "precision" Dell and I have some problems to install in mono boot in "EUFI" on 2 disks partitioned as follows:
/boot/efi (ESP) in fat32 + in ext4 / on nvme0n1
sawp + /home on sda
Salix Os or Slackel see Slackware. It seemed to me, however, that there was a way around it with ²Slackware current? Would anyone have the same kind of problem.
Thanking you in advance for your insights
Yours sincerely

Well, the 14.2 installer issue is on NVME disk. Which you can fix by using this info.
UEFI boot should not be an issue.

I guess you need to provide more information or error message to get help.

Thank you very much Lougavulin for your help and apologize for the delay in my answer due to my professional activities.
My initial project was to install SALIX to familiarize myself with Slackeware. I tried to install both without success. Alien Bob's Slackware Live alternative seems to give the possibility to install the "current" version on a SSD. I haven't tested it. A few days ago (parental duty), I gave my daughter my test machine. Considering your connection, which I keep aside, it seems that there is a need to put my hands in the sludge, which I will not hesitate to do despite my current state of knowledge which we could call rudimentary, but, to tell you the truth, I am reluctant to try the experiment on my production machine (Computer Graphics and Architecture). I will therefore support Patrick Volkerding, and wait until a version 15 can be implemented in the Salix. Computer science teaches patience, doesn't it?
Thank you again for your message and for the time you have given me. As soon as I get a PC back, I'll try this solution in the meantime.
Yours sincerely
