Linux is not installed as a second OS?

Question

linux

Hello.
Already before there was Linux as the second OS.
But then, something went wrong and he flew off.
I want to put again. I downloaded a new distribution kit from https://www.deepin.org/ - the same ubuntu, only the design is different.
Set bios to boot from sd drive. An additional disk for Linux was created 20GB. And when I reboot the laptop to complete the installation, nothing happens. Just a welcome window from LENOVO and that's it. After a while Windows loads.
Windows 8.1 lenovo laptop.
How to solve this problem. I also tried to insert a distribution kit from Linux debian, but also without success!

Answer 1

If you have UEFI: disable SecureBoot | Enable compatibility mode (CSM) with bootloaders for BIOS. Perhaps your boring distribution did not include an EFI bootloader.

Answer 3

Here it is advised to disable EFI and use the old CSM method.
But this is bad advice.
When loading, go into BIOS and manually select the item - boot from CD (I have it on the last tab in BIOS).
Put.
After installation, do not forget to register a new OS in the EFI bootloader, otherwise you will have to go through the BIOS every time you boot and indicate where to boot from.

Answer 4

Customize the boot order or simply use the key to call the boot device selection menu (see the user manual for the laptop).
