Hi,

I have finally managed to install ubuntu on a 128GB SD card which dual boots with windows 10. However, ubuntu works like an old guy. It comes up so slowly. It tends to halt and overall very slow function.

Does this slow function mean that it is a bad idea to install ubuntu on a SD card or it means that there is something wrong somewhere?

No. I ran AntiX, MacPup, GuyDog < on a 128MB sd card>.

On a Compaq cq 56. Probably more low powered than what you are currently using to post this thread. Just a guess though since you did not say anything about that. < I really need to windex my crystal ball>.

Ubuntu is with Gnome desktop is kinda heavy on sd. What class is the card <6?>. Read write speeds. How fast is the SD slot
on your computer? What linux file system did you format the card as?

I made sure my Linux install was a frugal install and ran in ram. So no. Not a bad idea.
You probably are just learning and do not have a good idea yet on how to run Linux off a sd card is all.

It takes a bit knowledge I guess.
Not bad for 1st try though.

That's right. But, good to know that installing linux on SD card is not a bad idea. However, it is taking me so long to start ubuntu on a SD card with class <10> and firefox has a hard time to launch. Here's what I've done:

There is this Dell inspiron 11 with 28GB capacity and windows 10 installed on it. I want to install ubuntu on an SD card with 128GB capacity and make a dual-boot system.

So, I wrote ubuntu iso file on a usb flash with dd and installed ubuntu by changing the format of the SD card to sdb and left the mounting point as default.

You can install any Linux (or BSD) system on SD cards, microSD cards, pendrives, or external disks.

Some can be slow to work, depending on your media, but if that is the case, booting to ram speeds up using it.

Another way to use small external media is to use persistence, read up about it.

Hi.

Some devices can be more long term than others but any can fail*.

If I love an SD for my Raspberry Pi, &c., as cheap as they are I keep two*...( Pis and SDs ) there are "high speed" SDs as well.

Have fun!

yes it is going to be slower booting up because of throughput limits.

Might help. Might not. It is a older article.
