So I have this Lenovo AMD A6 laptop with 4 Gb of RAM and an HDD (not SSD). And under Windows 10 it is s-l-o-w, but my wife uses it and she has one indispensable Windows application.

I would like to make this a dual-boot machine, so that if Linux proves much faster, we could try that application under WINE, or try VirtualBox with some very old Windows in it, or, finally, see if an open source replacement can be made to work for her.

But it's a recent laptop so it has UEFI and Secure Boot and all that. Also, no optical drive at all, of course.

So what can I do to make this into a dual-boot machine with OpenSUSE?..

other have given very good advice, I will add one. read carefully the computer manual to see if by chance there is an other hard disk port many computer, starting already 5 or 6 years ago, have a naked msata or (better) nvme port. This allows to add a second fast and very small factor hard drive. these ports use hard disks of the size of a credit card (msata) or a ram chip (nvme), so small it's nearly incredible. I found a msata port on a lenovo yoga computer and on a dell vostro, this allowed me to *add* a very fast hard drive. if you get a *pci* nvme, it's even a better bargain. on my lenovo the interface is under the keyboard. The exact serial number of your computer may give the anwser from the lenovo web site. for the dell it was not quoted in the manual, but easy to see in the ram slot. if you don't have one, I urge you to change your disk to a ssd model. Prices are low and speed will be much greater. what I would do would be to shrink windows 10 as said by others, then clone the disk to ssd with clonezilla and only after that replace the disk of course, first try a live image if you find one, but the ssd will help you even with windows jdd -- http://dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
