Lenovo IdeaPad S205 - BIOS access via F2 doesn't work

Hello,

 

all the time i had Windows 7 64Bit working properly, cince i have tried to install Ubuntu 11.04 i am not able to boot from HDD. Windows 7 and Ubuntu installations are able to find and partition the HDD, XP installation can't find HDD.

 

I think there is no HDD issue, i can not enter BIOS by pressing F2 Key, the BIOS is trying to boot by 3 times and stops at the menu where you can shoose the boot source.

 

So what is the problem of the bios?

 

Thanks and sorry for my bad english

check if there is bios update and/or try this trick:
remove the battery, un-plug the ac adapter, press power button for 30-40 seconds, replace the battery and set default settings for bios.

It didn't work, there is still the same.

 

Boot Menu

1. Windows Boot Manager

2. ATA HDD0: HITACHI HTS545025B9A300

3. PCI LAN: Realtek PXE B02 D00

4. PCI LAN: Realtek PXE B02 D00

 

with tab i can switch to App Menu, but there is nothing, F2 still doesn't working. Is it a bug of the BIOS? Looks like a bug for me.

Hi,

 

did you install Win7 64Bit? If so, you probably used UEFI mode with GPT partition tables!

Thats a common issue on the S205 BIOS. Shutdown/StandBy and WiFi problems occur all the time and there is no fixed BIOS available. Just google "S205 win64 uefi".

 

You need to re-install using legacy BIOS mode. To do that, you just wait, while your Win7 DVD is loading and don't press a key. Then clean the HDD and create new partitions as needed.

 

Hope that helps,

witteks
