Well... I, who have almost no knowlegde of Information Technology, did a dual boot on my computer to install Windoes 7 and Xubuntu, using Unetbootin to do it without USB. I really don't understand enough about partitions, but I created a non-allocated one (only did this, and doesn't seem to change anything) It didn't blow up, but here are some problems:
in boot screen this error appears, and I don't what is this https://cdn.discordapp.com/attachments/334723231804162059/650863996903358484/Capture_2019-12-01-22-00-34.png
The next screen, the loading blue Xubuntu, takes too long to load, everytime.
The clock is wrong, also on Win7 (only if I change to the other OS, otherwise it continues ok).
I don't know what should happen, but the partition keeps being "non-allocated", both on Win7 and Xubuntu https://cdn.discordapp.com/attachments/334723231804162059/650860335510847489/xuuu.PNG Yep, I didn't not configure anything after creating it. And sorry for the Portuguese text.
Xubunto doesn't seem to save ANY data after I restart it, being like new.
I apologize if did something stupid and extremely evitable. And ask for please be ditact. I have no idea what I did wrong or how to fix it.
