Desktops & All-In-Ones

[Ranier]

Hi, wanted to know if you tried disabling secure boot, and what were your results. I'm really interested in buying this PC mostly for HD video editing on APremiere and AfterEffects, so I don't know if the G630 is good enough for that. Assuming that It isn't, I'd really like to have the option to upgrade whenever I want. Thank you!

   In my case, after swapping in and out video cards a few times, the machine would only make it to the acer BIOS splash screen with even the stock video card.  

  I could get into bios, but the screen turned solid green and you couldn't see anything and had to operate the BIOS blind.  I knew the machine was not locked up as I could hit F10 enter to save bios and exit and it would reboot.  I could also let the system boot into windows and watch the hard drive light booting windows and hear the chime through the speakers once in windows, but there was no video at that point either with the stock video card.

  In my case, booting once without a video card somehow corrupted or changed the UEFI configuration and it was then acting as if it was locked to the integrated video and would not recognize the GT630 stock card either.

  I reset the BIOS through the motherboard jumper, and by removing the battery, and neither helped.  I also attempted to turn off UEFI blind in bios by using the comput'er's service manual and looking at the BIOS screens in the manual and operating the BIOS blind (without video).  This did  not work either.

  Honestly, I'd advise avoiding this machine if you plan to upgrade video.  I am 100% certain I damaged nothing in this machine, and in a previous post I mentioned changing the motherboard and having no issues (and even having luck getting the old windows 8 install to work on the new board without a reformat or repair install).   The issues are definitely tied to this OEM acer motherboard.

strange that this thread is an Re:

to a thread i had started 2 weeks ago

anyway, i shall repost here....

the solution seems to be

http://acer--uk.custhelp.com/app/answers/detail/a_id/27071/~/how-to-enable-or-disable-secure-boot

disable secure boot And enable launch csm

note: i had upgraded bios {though this may not be necessary}

the update is available on an acer page, then i followed the instructions on the page above

after doing this, i removed the original gpu, inserted the 'third-party' gpu

the computer, with its new gpu, is now fully functional

i hope this solution works for everyone

You need first to enter the bios when the graphics card that comes with the computer is still installed.

Just press the del key on startup.

Then makes the 2 following change in the bios:

1- Change Authentification to: disable secure boot.

       This enables the bios to manage equipment not installed originally.

2- Change Launch CSM to: always.

Then save your new settings.

The computer will reboot.

Shut it down to install your new graphic card or SSD, HDD...

Reboot and everything should be fine.

I have changed the graphic card to GTX 660 TI 2 GIG, the power supply to 500 W and also installed a SSD drive.

This makes it a much more powerful machine, like in gaming. 

This works except that the computer now does not recognize any additional disk drive, including the 2 Terabytes HDD drive installed.

I have tried 2-3 HD, connecting them directly inside the computer but to no avail.

The computer takes a very long time to boot, if I press F12 to choose the loading drive, I can see the additionnal drive, then I load my SSD drive where my WIN system is, again a very long time before it finally boots.

Around 5 minutes.

If I then go into explorer to view the disks, the new drive does not appear.

I did not find any documentation on the meanings of the settings in the bios.

Any solution would be appreciated.

For those looking to upgrade cards, was space an issue? According to some, some of the more high end cards that would work with the PSU may be too big. Does anyone have the information regarding space for a new card once the older is replaced? Most of the cards I'm looking at now are between 8-10.3 inches tall. 

For example, both the AMD 7850 and 7870 are 10.2 inches tall, double slot, and 4.5 inches wide.

The Nvidia 660GTX is 10.2 inches tall, double slot, and 5.2 inches wide.

Should I expect any problem fitting these?

I did install GTX660 TI and its operational.

Can overclock with great performance on FC3.

The card fits tight, cables are to be carefully push aside.

Recommends purchase and installation.

hit Delete when the acer screen pops up, and then disable secure bot and then and then Launch CSM its all in this video on youtube. https://www.youtube.com/watch?v=5nG4zMdrHKs I plan on upgrading to a GTX 660 myself for I am a hardcore PC gamer

I got the same problem that is how to change bios to recognize legacy mode and disable secure mode in order to bring in my GTX 650 TI. After many tries (when the GTX card was installed), I removed it and put back the original video card supplied with the computer. Then I could have video mode on my screen and access the BIOS on start-up.

I made the changes stated above in the BIOS.

I reinstalled my GTX card and the computer reccognized it on start-up and is working great graphics through it.

I also improved the supply to 600 Watts, but its not necessary as the video card will draw no more current then available, in other words if supply is too low, the video card will still work but with diminished performance. 

My problem remains unsolved as the computer wont recognized additional disk drives input.

The computer will take 10 minutes + to boot, the available drives to load from on start-up will show that the drive is there, but no programs under WIN 8 can find it.

I tried different power suppplies and disk drives, to no avail.

Honestly, I played a lot with cables, changing video cards, instaslling the new power supply and its cables.

It occupies far too much space to my confort, and I do not mind about voiding the Acer warranty.

Its my computer and I want to boost its performance to max according to my means.

I did not find proper documentation on these subjects.

Also its impossible to overclock this machine.

It still remains a good installation and overclocking the GPU makes this computer a very performant system for gaming.

To finish the story, I use the computer with the GTX 660 Ti, which is easy to overclock, and the only drive is a SSD of 240 GB.

Win 8 as system.

This is very fast for all programs, specially gaming.

Accepts well new equipments like gamepads, advanced mouse.

Wont change anything else, not worth or not possible.

Should be good for a couple of years hopefully.

I'm having the same problem right now with GTX760 or even bigger problem, since I have Win7 (its UR20P) on my machine and there is NO option for Secure Boot in BIOS nor UEFI available. I upgraded to 650W / proper amperage on 12V PS, but it didn't help. I replaced the card with Amazon to eliminate the possibility that the card itself is broken.

Reading the above I suspect that the card was fine - I could see both of its fans turning, but the computer was stuck at the Acer/bios screen and woulnd't boot. I just updated BIOS and I'm waiting for the card replacement...

Is there a way to get to Secure Boot option from Win7?
