Stuck in UEFI after reset to default.

Hi,

After resetting UEFI to default values, I can't start WIndows because boot goes to UEFI.

The story is this:

I wanted to make a clean install of W10 and for that I had to make some changes in UEFI because it wouldn't allow me otherwise. But after the installation I see that I have some problems with the sleep and fast boot, not working well. So I went to UEFI and reset it to default, saved and exit. On boot, it goes to UEFI once and again. Windows doesn't load.

So I have to do the same changes that I had to do for installing W10. Disable fast boot, etc. And then yes, I get to Windows, but keep having the same sleep and boot problems. Both work really bad in different ways.

Does anybody know what is wrong?

PS: I also did other changes, by the way. I couldn't install W10 because it said that my disk was GPT partition style, so I had to follow some instructions to change that, which wiped my disk and partitions completely and maybe I missed some step...

Thanks in advance.

Here you are.

but gives more flexibility in future.

It depends upon the flexibility to do what the user is seeking. Do they want more and larger partitions? Then that would be true. Do they want flexibility to multi-boot things like Linux, Macrium Reflect ISOs and MiniTool Partition Wizard ISOs? Then MBR and Legacy booting is more flexible.

I got lost, sounds like chinese to me all of that...

This is what I have in the UEFI Boot:



So, when I try to change the Boot configuration or when I try to reset everything to default values, I can't boot and get into this UEFI thing all the time.

I don't see any "Legacy" thing anywhere.

Thanks a lot.

Let's see. Since I couldn't install the W10 iso because my disk was GPT I followed these instructions found in a web site (Solucion el disco seleccionado tiene el estilo GPT. - Taringa!)

diskpart
list disk
select disk <disk number>
list partition
clean
list partition
list disk

And maybe there is some mistake because later I found these other instructions in a Microsoft site, and in this one there is different commands, such as "convert gpt" that I didn't do:

Configuracion de Windows: Instalacion mediante el estilo de particion MBR o GPT

diskpart
list disk
select disk <disk number>
clean
convert gpt
exit

¿Could this be the reason?

What I want is to have a sleep mode and boot that work well again, as they did before I touched all of that, as when I had my default W8.1 from factory untouched that worked great (the laptop is new from last summer).

I want to have sleep mode, fast boot, etc, and have all UEFI values as in default mode, so that nobody can install Linux or anything else or boot from something else without my permission.

Many thanks
