Do you have the BIOS configured to use the SATA in PATA mode (all drives are IDE unless you go back to 1980)

I dont think so because my windows recognize the ssd...
How can I check it?

How you checked that Kubuntu recognized the SSD as IDE ? The slowness of the system can be related to many things also.

Lets see some results

sudo lshw -businfo | grep -e storage -e volume

sudo parted -l

sudo fdisk -l

First of all , this is not a regular installation of Ubuntu. Wubi.exe is almost a virtual installation.

The SATA Controller [ACHI mode] probably is your SSD. To enable trim on SSD ACHI mode should be enabled , some motherboards have this by default.

As for the IDE controller.. I'm not sure , but look if your MB has one.

And the slow system , I guess that this is due to wubi.exe installation. Yes , wubi is slower than a regular install because of the virtual hard drive. Ubuntu is not running on native filesystem (ext4) but on a virtual HDD inside Windows.


Can you help with this problem?
