Hello, i have this computer Acer aspire v3- 731 and it has windows 8 operating system that i want to change to windows 7... There is this small problem with that operation. I would need to boot the computer from cd drive and i cant change the boot devices because the bios is password protected. This is an used laptop and the person who sold it does not seem to know the password.
I have tried all kinds of tutorials and tried to get the error code from the bios to crack the password but this computer model does not give the error code which you get after entering the bios password wrong three times.
Taking out the cmos battery wont help either.
I did a bios upgrade but at that point i did not modify the files to disable the password protection. IT now has bios version 2.23 and i want to downgrade it to the bios version 1.14 with the modified bios setup file but it gives me an error saying that "please update to the same type of bios 2.23" I have tried to modify the setup file to get rid of that message but it wont work no matter what i do.
I add the setup file with the modifications as an attachment to this post if someone can take a look and perhaps tell me what is wrong with it... I packed the files with 7zip and i hope it's legal to put them here. Thanks!
I could only add the platform.ini file as a txt file because of restrictions but i put here a link to the full setup file so if someone can tell me what's wrong with it... Here is the link... hxxp://s000.tinyupload.com/index.php?file_id=01734563086413735823
So that no one will not accidentally click that link i changes the http to hxxp so you must then manually change it to go to the link destination. Ok. Thanks.
