"installation crashed" while installation was about to finish.

[Md Rahatul Islam]

Its my first time installing any linux distros (ubuntu)..Before i only used windows 10 pro . I was installing ubuntu from usb driver.. last few days I have run ubuntu from the usb drive as well.. everything was fine.. didnt face any error ..Then I decided to shift to ubuntu as main OS.. i was installing by selecting "erase disk and install ubuntu" .. after installation started, everything was going well until at the last moment a windows pop up saying"installation crashed" .. I really have no idea about it.. Please can anyone help me to solve this? and will this make any major problem to my system??

note: my device is Acer Aspire A515-52G-57N3 with 2TB hdd..and this is my first ever question on this site so if any mistake please forgive me.. Thank you!

Hello, I'm not sure of the cause of your installation problem, but I did see firmware errors in the logs, as well as the windows filesystem wasn't cleanly unmounted. It might be worth installing BIOS updates from Acer, if any are available, and perhaps also using a 'restart' with windows, and not letting it get past the bios. (Windows 'shutdown' apparently isn't an actual shutdown these days.)

I hope this helps. Thanks

Thanks a lot for your email.. I would like to inform you that after that
problem i shutted my laptop down and turned it on again and then i saw it
was working properly..then It asked for some updates.. But from my
curiosity i searched about it and found out the solution from askubuntu
site. and that was very simple that saying not to check the box of allowing
third party app before installing what i did watching youtube tutorial..
Then at the second time i didnt check that box and went for the
installation process and then it worked perfectly..Now im working on ubuntu
without facing any major problem till now..

I will be very thankfull to you if you kindly let me know that *is this a
proper solution of that issue or not? Can i use like this in future?* And
also im confused about if my laptop is ok to use linux on it? because i saw
the list of certified devices thats hardware can run linux on it and theres
no Acer.. So as you are an expert please can you tell me about it? My
device is Acer Aspire A515-52G-57N3.

*Thank you!*
