No Bootable device issue after Installing Kali Linux - Acer Aspire ES1-533

[bsmith]

Hi,
I have purchased 3 Acer Aspire ES1-533 Laptos , I just tried to install Kali linux , created bootable disk using Rufus , and it was a GPT/UEFI compatible USB drive. But after my installation the system shows no bootable device found. Please help me to fix this.
In bios there is no option for changing UEFI boot type.
I have tried many options which are available in the internet.

• Contacted Acer customer support
• they simply neglected , by saying we are not supporting Linux
• Tried many ways, dome morethan 10 times installation
• some technicians told me to update BIOS from 1.08 to another version
• But updating BIOS will affect the performance of PC

Friends I have no life without Kali...

Thanks in advance
