Hi
@atanere my laptop came without any CDs. So I don't have HP recovery CD.
Ok i'll Reinstall both win10 and Linux and start HD from scratch.
So witch Linux distribute you suggest and are Ubuntu Apps can work on it?
Also you said "Do not encrypt the Home folder unless privacy/security is greatly needed."
But I don't know where can i found this option?
Also after install linux do you want me to use repair boot command in terminal or not?
There is an APP called "APTonCD" This tool will allow you to create a media (CD or DVD) to use to install software via APT in a non-connected machine, as well upgrade and install the same set of softwares in several machines with no need to re-download the packages again. So if i use it Is That effect on new Ubuntu i installed or not?
Yes i understand that Don't worry

i delete those partitions because i know that the worst case is reinstalling Windows 10.
Thanks
Hi
@Yara. The big companies (HP, Dell, Acer... all of them) stopped including CD's or DVD's a long time ago. But I think that all of them include a program that lets you create your own Recovery Set (to DVD or USB). It might take up to 4 or 5 DVD's to make such a set, but it is a good idea to do this shortly after you buy a new computer. This "factory recovery" is also on the hard drive... but if hard drive failure is the problem, you need the backup Recovery DVD/USB to restore your computer after getting a replacement hard drive. That's the idea, anyway. You may can still create the "factory recovery" using the HP app.... unless it happens that the
/dev/sda1 partition is the one that HP uses to create the set. If you have spare DVD's (or a spare USB stick... probably 32 GB needed) it might still be worthwhile for you to create the HP Recovery Set. This set would include all of the HP-included programs and extras that came with the computer when it was new.... some people like that stuff, some people don't.
The Windows 10 .iso that you downloaded will only put Windows 10 back on, without all the extra HP tools and software. I have used this Windows 10 .iso myself to restore my computer without all the HP stuff, and Windows still "activates" as a registered version with Microsoft. This is under that category of "digital license" from Microsoft... basically when you activate Windows, they recognize your computer and know that it is a legitimate copy. This is still a good backup to have, even if you make a HP Recovery Set too.
If you have both.... then you can decide which to install to restore your computer and start all over from scratch. And you will have the option to change your mind and switch to the other too, if you decide.
Which Ubuntu? Right now, that is a good question. I read more today about the "bug" that has been found in 17.10, and it can cause problems in some HP computers too. I don't think mine was affected, and I don't think yours was affected either.... but I'm a little nervous to keep working with 17.10 until Ubuntu releases a fix for this. This bug is very serious, and if it were to damage your computer, it might require a new motherboard to fix it. And if you had to replace the motherboard, then Windows 10 would NOT activate properly anymore either.... that would be a bad situation.
Right now, if you are anxious to start making big changes... I would say to pick your Windows 10 option and use it to restore Windows 10 first. Let it erase all of your partitions, and let it install itself how it wants too. It will create at least 3 partitions (Recovery, Microsoft Reserved, and Basic Data).... and maybe more. Looking again I see that you now have 3 Basic Data partitions.... one of those is Windows, and Windows may have created the other 2 also, or maybe you or your brother created them.
Remember to backup anything important before restoring Windows 10.... it will erase everything!
I am hopeful that Ubuntu releases a fix soon. And maybe by working with Windows for a day or couple of days, perhaps that will be enough to see a new Ubuntu. If not, you might want to use their last "long-term" version, 16.04.3. and install it for now. The next new Ubuntu will be out in April, and you will be able to upgrade to that, which I think will be pretty easy. There are some differences between what you've seen with 17.10 and with 16.04.3.... but I think that they are minor enough to not be much trouble. The new version in April (18.04) will be more like 17.10. Have you figured out yet that Ubuntu versions are based on the date? So 17.10 was released in October 2017, and 18.04 will be released in April 2018, and 16.04.3 is the "3rd update" of the one released in April 2016.
APTonCD.... I don't think you'll need that. If you have a good internet connection, it is better to get software online so you know you're always getting the current one.
Encrypting the Home folder... this option is just a "checkbox" during the Ubuntu installation (on the screen where you create a user name, and password... located near the bottom, by the selection to "log on automatically"). It is not checked by default, and I usually discourage it (unless very seriously needed) because it brings added complexity to the file system. But if laptop theft, or other security reasons are a concern, it is an option for added privacy of your data. Since I don't use it, I don't really know how it works.... you may need to create another password to protect the encryption... and of course, in that case it should be a very strong password (or pass phrase).
After you install Ubuntu, you may need to try the
bcdedit at the Windows command prompt to make GRUB come up instead of going straight into Windows. Of course that is the battle we have been fighting all along!

This command worked for me with a fresh installation, and I am hopeful (again) that if you do a fresh install that it will work on yours also.
I can go through the Windows 10 installation steps with you again too, if you want. It's no harm to the computer to do that. If you if have troubles, you may go through the re-install an extra time or two also to make everything just right. My only limitation right now is time... because I have to work for 2 more days before I get a few days off again. I can't help or follow along from work very well (although I do try to check in and see what's going on when I get breaks).
OK, enough for now. No need to rush, but if you're ready to erase a computer.... that is usually pretty easy to do!
Cheers
