Bought a new laptop, installed Win 10, and then installed Kubuntu

It was running Win 10 fine for a few days.

I installed Kubuntu to have a dual-boot laptop

but the problem is

After installing Kubuntu 20 LTS

the GRUB 2 show when I turn my laptop on

but it does not show Windows

And when I enter Kubuntu, Kubuntu does not recognize Windows partitions

Perhaps you overwrote your Windows installation? Which partitions does Kubuntu recognize, and how did you check that?

Haven't we been here before??

...where you also didn't follow up. If it's a new laptop, you can either do a full restore of Windows and wipe out Linux. And do an install where you actually follow an installation guide (here is one of MANY you can look up for yourself):
https://www.ubuntubuzz.com/2020/09/h...nal-drive.html

Or you can post some details about your partition structure, what you've done/tried so far, etc. Typically the Linux installers will automatically set up dual-boot, but you don't say how you did the install, what you see on the menu, or give any details. Since you've now been using Linux for *TEN YEARS*, you should be easily able to provide these things.

Caveat: I'm not a dual-booter anymore. The problem could be as simple as a missing section in the Grub config file that corresponds to the Windows OS.

Before performing surgery on the Grub configuration, try issuing the following to get a report of what partitions you actually have on disk:

Code:

$ script fdisk-command.log

Script started, file is fdisk-command.log

$ sudo fdisk -l

[sudo] password for root: <whatever>



<fdisk output>



$ exit

exit

Script done, file is fdisk-command.log

$

You should see the partition tables for all attached disks. One disk should have a Windows partition listed (in the far right-hand column) of one of the partition tables. On a laptop, there's likely only one disk/one partition table.

Either upload/attach that log file (see the "Additional Options / Attach Files" pane) or issue "cat fdisk-command.log" and paste the results into the Message pane, highlight it, and enclose it within "code" tags. (See the "#" above the Message pane.)

Good luck...

opne a terminal post the ouput of the following:

Code:

sudo parted -l

cat /sys/firmware/efi

More information is required as suggested above but 2 common reasons for this scenario are installing in different modes, windows likely UEFI and Kubuntu Legacy or having left windows hibernated so that the windows partitions will not be mounted/accessible.
