[Solved] Lenovo 100S-14IBR - Win 10 installation from USB does not start

Hello,

I wanted to put back a fresh Win 10 64bit Home system (this is how it is now). The Netbook is the Lenovo Ideapad 100S-14IBR.
Unfortunately, I can't start the installation with a pendrive. I created a bootable flash drive in Rufus. I have already checked all the options, creating:
GPT for UEFI on FAT32
MBR for UEFI on NTFS
MBR for BIOS or UEFI on NTSF.

Bios updated to the latest. In the bios settings I also tried with different settings:
OS Optimized Default: with Disabel and Enabled
intel platform trust technology: with Disabel and Enabled
Boot Mode: UEFI and Legacy Support (UEFI first and Legacy first)
Secure boot: with Disabel and Enabled

And various combinations of these settings. USB boot on Enabled of course.

When turning on the device with the recovery key and selecting the boot menu, or clicking F12 when turning on to display the Boot menu, the pendrive is seen. Despite selecting boot from this USB stick, the netbook starts normally. And so every time.

PS flash drive is working and the image is ok because I have a second Ideapad Y510p with almost identical bios and there is no problem with me installing from this flash drive.

Yes ISO image.
That's exactly what one of the settings that I tested looked like.

Use USB 2.0 port. Turn on UEFI mode in UEFI. Pen won't boot in UEFI mode as the file system will be NTFS @Tubelerczyk .
Alternatively, the laptop has a general problem with switching from HDD to USB. It happens.
Therefore, you can either format the disk so that it cannot be booted, and maybe the hardware will look for a USB bootloader or you can use my favorite method "in Khams":
you disconnect the HDD from the interface, boot USB and once it starts booting you connect the disk again.

And again ... Rufus (instead of MCT), and when you add to that that there was no "verification" of the start in other equipment, you can guess freely whether and what to turn on / off to maybe It worked.

Maybe the dear colleague did not notice, but there was verification - the pen starts in another laptop:

In this case, I must think carefully whether to permanently stop recommending Rufus to MCT. To do this, however, I would have to use it myself a bit, and I have no experience. Maybe he would actually set the right settings "from a machine", which I am as afraid of and I expect.
By the same I understand "disgust with Rufus" (and this kind of cute duck was in a fairy tale), but to tell the truth its effectiveness is nothing less than 100%. I did not notice that pens prepared with it booted worse than those prepared with other programs.
As for the boot settings in UEFI, I will refrain from commenting, because what is currently happening with this technology goes beyond the capabilities of the average PC user and if nothing changes (and it looks) even a beginner "IT specialist" will have big problems with implementation the simplest activities in UEFI like booting, OS installation or activities on partitions with "WinRE" with WinRE.
You don't have to look far. I damaged OS in UEFI in one of the laptops and I can't fix it for People's China:

Damaged BCD, damaged Recovery, clutter in boot entries in NVRAM - sit down and cry. A miracle that the system is booting.

I didn't notice - sorry for the mess.
By the way: MCT - I definitely do better with it than with Rufus.

For peace and certainty I will write that the image created by MTC did not work either

Choosing Restore Factory Keys helped with Secure boot. Pendrive in Rufus on GPT for UEFI in FAT32 and installation went without a problem
