I installed the latest version of Lubuntu (which I also want to change to normal Ubuntu in the end) on a LENOVO ideapad (don't know how to get details on the laptop on lubuntu) but I cannot access Windows anymore. I don't have any disc or anything because the laptop was ordered from internet and has no shop I can go to neither any recovery disc so. I don't want to erase windows neither change it also because it is still under warranty.
I would like to erase lubuntu which has no audio interface and also I believe is way too minimal, be able to access windows 10 again and install Ubuntu on a different partition in dual boot. (so far I believe they two OS are on the same partition)
Any advice?
So far, I managed to uninstall Lubuntu and install Ubuntu.
I still have the problem with Windows, I started following the instructions given below.
First of all I realised it's windows 8 so I assume the UUID is different?
Second, do I have to copy and paste the window or change the UUID …and as for the position, I don't see where I can type ('hdo,msdos1').
Thanks for your help so far. If a boot-repair is better I can try again now that I can work from Ubuntu directly.

You will be better off in the future if primary OS is backed up prior to the installation of another.
First, preferably, we have to discover a path that let us boot you into Windows.
Assuming that Lubuntu filesystem has not overwritten any bit of Windows (highly probable) and GRUB is installed with Lubuntu on default you can let
os-prober
do the job.To be on the safe side, change
/etc/default/grub
settings:Type into CLI:
Check whether
grub.cfg
resides in/boot/grub/
If positive, try:
If
os-prober
(which should be on default turned on) found UUID of Windowsbootloader
partition, you can reboot the system, choosing Windows when dialogue appears just after BIOS.If
os-prober
failed, we would manually provide GRUB with location of Windowsbootloader
partition.To do this, we have to obtain Windows
bootloader
partition:Probably it is in position of
/dev/sda1
:Now, as we know UUID, we have to adjust this piece of code:
Change UUID (SPX7ZJUBC2EN7FAH) and position ('hd0,msdos1') of Windows
bootloader
everywhere.Paste code provided into
/etc/grub.d/40_custom
and save.Then, once again, put into CLI:
Reboot.
Before you erase Lubuntu, try to change desktop enviroment for e.g. MATE:
Install MATE how-to
I think it would be enough for enriching your computer experience and would make all functionalities available easier.
