Hello,
I need to install Windows 7 in UEFI mode using USB flash drive and for this purpose:
- created Windows 7 UEFI bootable USB using Rufus application
- In BIOS choosed UEFI Hybrid boot option with CSM
- disabled switchable graphics
- disabled fast boot
- secure boot is disabled
When I reboot and choose to boot from the USB using F9 boot menu, the computer continues to load my current system from my HDD and not the UEFI from the USB.
(I used the same USB and Windows 7 and succesfully installed windows in UEFI mode on my desktop machine but the laptop doesn`t want to recognize the USB as a bootable.)
I tried to put the USB on different slots but that doesn`t help.
Tried to boot from the UEFI USB drive in Legacy boot mode in BIOS, but no result.
My sistem is as follows:
System Model HP ProBook 4540s
BIOS Version/Date Hewlett-Packard 68IRR Ver. F.40, 29-Jan-13
SMBIOS Version 2.7
System Type x64-based PC
Processor Intel(R) Core(TM) i5-3230M CPU @ 2.60GHz, 2601 Mhz, 2 Core(s), 4 Logical Processor(s)
I searched the HP forum and the internet for a solution but nothing helps.
Cindly ask for support. Do anyone have or resolved the same problem?
Regards.
