They brought me a laptop the other day ASUS X541N. They asked me to install Windows 10 or Windows 7. I have a multi-boot flash drive with different versions of operating systems, which I did a couple of years ago. I stuck this flash drive into a laptop, turned it on and began to press a key on the keyboard Esc. I thought that I could quickly manage the installation of Windows, but it wasn’t there.
After pressing a key Esc a window appeared prompting you to select a boot device. But on the list there was no my flash drive – there was only a laptop hard drive. I went to the “Enter Setup” item in this window. Before me on the screen appeared a modern UEFI BIOS of an ASUS laptop – BIOS Utility – EZ Mode:
Moreover, in the UEFI BIOS my flash drive was displayed in the “USB port”But under“Boot priority”She was not there. This meant that I could not select it as the boot device, and install Windows from it.
Then I decided to try change BIOS settings – I already did this with a Lenovo laptop (he also had UEFI Bios). I will say right away: if this helped in the situation with Lenovo, then it’s with by this ASUS laptop change settings did nothing:
I switched to “Advance Mode” – in the section Security disabled secure boot protocol (set parameter Secure boot control in Disabled): Next in the section Boot disabled parameter Fast boot (fast boot): Then saved the changes and rebooted. After rebooting, I again entered the BIOS section Boot.
But in this section there was not and did not appear the option “Launch csm”(And no other similar, for example:“ CSM ”,“ CSM Boot ”,“ CSM OS ”,“ Legacy BIOS ”). In other models of ASUS laptops, after activating this option in the Boot section, it became possible to boot from a USB flash drive.
And now I’ll tell you how I solved this problem and still installed Windows on an ASUS laptop:
Modern laptops have UEFI BIOS. In order to boot from a USB flash drive in UEFI mode and install Windows on a GPT disk without problems, this USB flash drive must be formatted in the FAT32 file system.
Therefore, if the BIOS of your computer does not determine your flash drive as bootable, then first of all, check which file system it has.
I inserted my flash drive into another computer – I went into its “Properties” and saw that it was formatted in the file system NTFS:
Then I just cleaned it and recreated a bootable USB flash drive with Windows in the file system Fat32.
After that, I again inserted it into the ASUS laptop – turned it on – pressed the key several times Esc on keyboard. A window appeared asking you to select a boot device – and this time in it, in addition to the laptop’s hard drive, there was my flash drive. I selected it and started installing Windows. I didn’t even have to go into BIOS and change anything there. You can read about how to create a bootable USB flash drive with Windows in this article of mine.
