Dell Latitude E5430 BIOS Corrupted
Yesterday, I removed some entries from UEFI boot stack from BIOS. After that, my laptop is unable to boot. It struck at Dell Boot Logo. It neither goes into pre-boot assessment nor into BIOS or One time Boot Option. I think the BIOS is corrupted. Tell me how to reflash/reinstall BIOS.

To reset the BIOS settings:
Remove the battery
Unplug the system
Hold the power button for 30 sec.

Hi ahmedbilal,
You could flash the BIOS if the system goes to f12 boot menu. I could provide you the link to create a bootable flash drive and then flash the BIOS through that. However, as advised, it is only possible if the system goes to f12 boot menu.
You could choose to remove and reseat the RAM modules and check - sometimes doing this would make the system go to f2 / f12.
To default the BIOS entries - you could also try reseating the CMOS / Coin Cell Battery - download the service manual - http://dell.to/1idvekt - and check on how to do the same.
Keep us updated.

Now, I can access BIOS as well as Windows. But, It sometimes still unable to pass POST. When, that happens I removed the cell and then place it again and then it start working again. Please specify permanent fix.

Please update the BIOS and run the diagnostics as advised in my previous post and keep us updated.
