Windows 10 doesn't show the same partitions OpenSuse created and edited

English Install/Boot/Login

Hello,
actually I have an odd situation, I may feel worried something bad can happen to my data.

My laptop had
1 - SSD with windows 10 (NTFS) | 464 GB
a partition for Data (NTFS)
an empty fat32 partition
2 - HDD for extra data | 464 GB

(and Samsung Magician with overprovisoning)

Then I started install OpenSuse from the current partitions
I removed the empty fat32 partition
shrinked the Data partition
and created one partition for OpenSuse Leap 15.2 OS (btrfs) and another for boot/efi (FAT) and a third for Swap. They totally took 15GB I guess.

NOW:
I correctly run both the OS when I boot them, BUT

Windows 10 shows the old partition tables and doesn’t show anything of Linux neither listed in Disk management. The Disk sizes are THE SAME

OpenSuse shows the choosed partitions

Any idea? Can you assist me in understanding and carefully know if my data is at risk of deletion for overwriting or similar actions?

Hello, welcome to the openSUSE forums.

Well, just saying you think they are different does not tell us very much. You must show us what tjose systems tell and then maybe explain why you think they are different and then let others here decide if they concur with you, or if they have an explanation.

So for openSUSE (as root)

fdisk -l

and/or

lsblk

And for Windows I have no idea, but as you say above you saw something, you seem to know.

BTW, because you are new here, I have a hint:

There is an important, but not easy to find feature on the forums.

Please in the future use CODE tags around copied/pasted computer text in a post. It is the # button in the tool bar of the post editor. When applicable copy/paste complete, that is including the prompt, the command, the output and the next prompt.

An example is here: Using CODE tags Around your paste.

And for screenshots, you can use https://susepaste.org/Click Image somewhere top-right, let never expire, upload and post the link of the page her using the Globe button.

Regards,

Most likely that windows is set up for fast boot and has the partition table saved in memory. When fast boot is on - it does not reload windows after a shutdown - it is more like a suspend then resume.

You need to turn off fast boot in windows and reboot windows for it to see the new partition table.

Thank you for your replies. Actually I removed fastboot and rebooted (twice)

Actually Windows 10 still showed up the old Disks configurations, then at first reboot found “an error with the disks” and asked me to reboot. I did this.

After the reboot Linux boot disappeared.

Now I installed everything again with a different method.

New method was to shrink one sdb disk partition and create a raw partition, then on OpenSuse I used it totally.

I hope as long as I don’t change sizes or anything else Windows doesn’t destroy Linux.

Can I ask you a technical explaination for this ninja mode of Linux vs Windows? Would have been the same using Ext4?

WIndows really, really likes fast boot. Even if you turn if off, it may do it.

I finished up disabling hibernation in Windows, just to be sure.
