Acer Aspire E15 :: Can't Boot From USB (UEFI)
Feb 18, 2015
I'm having getting my USB stick recognized as a bootable device (installing windows 7 onto a system that came with windows 8.1 pre-installed, no optical drive)
System: Acer E 15 (E5-571), BIOS V1.15 (UEFI)
What I've tried:-Disabled Secure Boot
-Created bootable USB stick with Windows 7 iso, via 'Microsoft USB/DVD Download Tool' (on alternate Windows 7 system)
-Created bootable USB stick with Windows 7 iso, via 'Rufus' (on alternate Windows 7 system)
-Windows 8.1 Advanced Restart -> Boot from UEFI USB Device (No UEFI device recognized)
What worked:-Enabling 'Legacy Boot Mode': USB stick was recognized upon boot and loaded Windows Installation. HOWEVER, Windows 7 won't instal to a GPT formatted drive under Legacy Boot Mode. I've read booting in UEFI mode is the only way to get Windows 7 to install onto GPT.
What I don't want to do:-Format the drive, change drive mode to MBR to instal Windows 7. Why? Because then I'd loose the factory installation of Windows 8.1

Everyone: Absolutely cannot boot from CD-DVD even if I turn OFF Secure Boot and UEFI and my machine lists my CD-DVD as a boot option. When I then try to boot from the CD-DVD, I get an error message. (Optiplex 7010 Mini-Tower with Win 8 Pro 64-bit, an Intel i5 3470 processor, 8 GB RAM and 500 GB hard drive. It has BIOS version A16 right now.)
I started a thread on this issue in Desktop Hardware Forum - [URL]...

I am simply trying to boot from a USB or the disc drive in an Aspire E1-510p-2671.
I have set the boot priorities correctly.
I have turned SecureBoot off.
I have turned on the F12 boot menu.
If I turn the machine on and let it do its own thing, it loads Windows 8.
If I tape F12 to go to the boot menu so I can manually select something, my only options are Windows Boot Manager, or
If I have network boot enabled, I get two network boot options.
I cannot change SATA mode off of AHCI, and I cannot change boot mode off of UEFI. I have scoured Google for this issue and it seems loads of people with Acer laptops cannot boot from anything other than their HDD. Changing the UEFI option has fixed it for everyone I have seen able to switch it, but I cannot switch it. What is going on? Why am I being blocked from booting from particular devices/ports? Makes no sense.

After the upgrade to the current UEFI firmware, when I try to access to settings the BIOS ask me for a password. I'm absolutely sure I have not set any password (I hate BIOS passwords). Now I need to start from a USB pendrive and I can't change the startup sequence.
I've read the post about how Acer can support on lost or forgotten passwords("there are very few if no options available from the end user side"), but in this case I've not created any password, as I said

For the last 2 days I have been trying to install Windows 7 x64 in UEFI mode on my laptop but it seems entirely impossible. Whatever I do, the boot menu (F12) just won't show any UEFI devices AT ALL, just the normal DVD and/or USB options. Obviously when I try to boot from either normal DVD or USB, Windows 7 setup freezes at the "Starting Windows" screen, I'm pretty sure that's because it is not running the EFI bootloader of the setup.
For the record, I can't just install Windows 7 in Legacy/BIOS mode because it is then impossible to install the Synaptics Touchpad driver under Windows because the Touchpad device is not discovered for whatever reason.

So I have bought this Acer laptop for 1 year, and it's BIOS came with V1.0 didn't have UEFI setting, the default is LEGACY. After trying updating that BIOS version to V1.13 successfully, I still don't see the UEFI setting, when I check in a software called HWiNFO64 Program, it says my laptop BIOS is capable of UEFI BIOS. So my main questions are....How can I have UEFI setting in my BIOS? What should I do?
My specs: Intel Core i7-3630QM 2.4GHz, Nvidia Geforce GT 640M 2GB, RAM 8GB, HDD 750GB, Windows 7 Ultimate SP1 x64 (Will upgrade to Windows 8.1 Pro x64 if I can change my BIOS to UEFI boot).

I have a Acer Aspire E5-511P with bios Insydeh20. On UEFI it does boot USB-drive, even with passwords set. It boots on USB-drive with legacy set, but now my Wifi doesn't work. On older laptops no issues with UEFI, I just had to set boot order. And Wifi works just fine.

My Lenovo U430 touch came with a Samsung 128GB SSD. Since it was becoming a little on the small side, I decided to replace it with a Samsung EVO 250GB SSD.
My first thought was to clone the old SSD and then resize the partitions afterwards. I quickly ran into trouble, the cloning didn't work out. So I decided to begin from scratch. So I installed the new SSD and installed a bare Windows 8.1 Pro install.
Although everythings works one thing is still bugging me. For the new Samsung SSD to be bootable I must:
- Disable Secure Boot
- Enable Legacy booting
I thought all the necessary codes were a BIOS / OS thing?

I have just purchased a Dell Inspiron 17R Special Edition 7720. It came with a preinstalled Windows 8 (so 64-bit and mandatory UEFI boot). I want to use Linux (more specifically, Archlinux) for work and Windows for games, so dual boot is needed.
I almost completed the Linux installation except for the bootloader: I need to boot Linux from UEFI and didn't manage to do it so far. Here is what I did after I received the PC:
-Disabled Secure Boot; updated BIOS to version A12
-Resized the main Windows partition and created a few partitions for Linux;
-Switched to legacy boot mode and managed to boot a MBR-bootable Arch linux installation USB drive;
-Installed most of the system switched back to UEFI boot mode, Secure Boot off.
At this time I needed to boot the kernel from UEFI for the bootloader installation program to have mandatory access to the EFI environment variables. So I created an UEFI-bootable Archlinux installation USB drive (with a FAT partition) but so far I couldn't manage to successfully boot this drive from UEFI instead of Windows 8.
I think I really tried every single combination, such as:
different USB ports; different boot entries created with F2 boot setup, with different parameters; different orders for the boot entries; hit my boot entries directly within F12 boot menu.
No matter what, in UEFI mode the system always boots the Windows partition.
Also, I could not find any relevant manual or software documentation about the A12 BIOS on the Dell site, did I miss something?
The solution that the user described in this thread to UEFI-boot to a DVD did not work for me with a USB drive.

I received my Dell Inspiron 15R - 5520 laptop and am attempting to set it up to perform a UEFI boot to a Windows 7 (64 bit) installation. I am using bios version A11 which is the latest available.
If I use legacy, I am able to boot fine to the Installation DVD and install/use the system. If I use UEFI (non-secure boot), it will freeze during the boot process for a long period of time. I do not ever get to the GUI to attempt installation. I have tried clearing the disk partitions using diskpart -> clean to ensure it is not due to having GPT vs MBR and have also tried changing the SATA adapter to ATA vs AHCI.
Alternately, I am able to boot to, and install Windows 8 RTM in UEFI mode.
Before I get a lot of responses of "Don't use UEFI", the reason I purchased this laptop was for the purpose of dual booting between windows 8 and windows 7 for development purposes, and require the use of secureboot to properly test the software I am developing. If this laptop is not able to run Windows 7 in UEFI mode, I will need to return it and select an alternate vendor.

I just received my XPS 15 and plan on dual-booting Win 7 and Ubuntu. I'm trying to install both, but I have no disk drive boot option in UEFI mode, only in legacy mode.
How can I boot from a disk using UEFI mode?

I've finally managed to find someone to replace my optical drive with an SSD (wouldn't want to void the warranty, do we?) and I've got quite bit of a problem here. After installing Windows 8 on the SSD, I get the error "winload.exe missing or corrupted" and error code 0xc000000e. The installer automatically put the boot data on the original HDD, while the OS is on the SSD - and it seems the UEFI can't find the OS like this.
The OS itself seems to be intact, since pressing F12 at booting and selecting Hard Drive starts the computer normally.
I've tried to move the boot sector to the SSD, but it seems I'm missing something... Would a BIOS update maybe work with this?

Yesterday I flashed the firmware of my XPS L702X to version A19, which enabled UEFI boot mode. I decided to go ahead and try to install Windows 7 in UEFI mode on a GPT disk. Installation succeeded, booting failed however. Then I read a message on the web from someone who succesfully installed Windows 8 on the same machine in UEFI boot mode on a GPT disk. So I decided to try Windows 8 instead. Installation failed. Using the recovery menu from the Windows 8 installation media, I wanted to try and see how far installation had come and more or less accidentally selected in some "Advanced options" menu to reboot to my USB flash drive (where the Windows 8 files were on). Rebooted fine. Then I shutdown, using the regular option.
When I turned on my machine again, I found out that pressing either F2 or F12, for the firmware setup and the boot menu, respectively, didn't work anymore. The firmware recognised my input, as the text in the lower right of the Dell splash screen became lighter, but instead of entering setup or the boot menu went straight ahead to boot my existing and working Windows 7 installation on my first (MBR) hard drive instead.
So, in short, I am locked out of setup and the boot menu. I have already tried reflashing the firmware, but without any luck. What to do now?

I'm trying to install Ubuntu on an e6530. I changed a BIOS boot setting from Legacy to UEFI. Now the laptop doesn't even show me a BIOS screen at startup. The screen is backlit, so power is on, but shows nothing. The drive light flickers a few times, but no matter how long I wait, nothing appears.
I can't even switch it back to Legacy because I can't get into the BIOS. Hitting F12 after power on does nothing. Is there some way to get it back to Legacy mode? Or simply reset the BIOS to default settings?

I bought a ThinkPad 540p that comes with preloaded Windows 8.1. As I want to dual boot the machine I tried to select the Legacy Boot option in the BIOS/Startup tab, but I can't do anything as the option UEFI/Legacy Book is greyed out and locked in "UEFI Only". Below it there is an option called: -CSM Support that is also greyed out and selected as [No]. (below these options there is a little note with an asterisk saying "Unselectable for Secure Boot").
How can I enable the UEFI/Legacy Boot option again in order to dual boot the computer? I want to be able to boot from USB or from the CD Drive.

I have a Acer E1 522-3657 computer, which my son set-up for me but did not make the recovery disc(s). The unit is just outside of the warranty period when the hard drive failed. The hard drive just makes a clicking noise and after the logo screen appears it goes to a blue screen with a box that has the following message with in, "Default Boot Device Missing or Boot Failed. Insert recovery Media and Hit any key.....Then Select 'Boot Manager' to choose a new Boot Device or to Boot Recovery Media.
I have installed a brand-new Western Digital 1T Sata3 harddrive to replace the Toshia 750 GB original Drive. After turning the computer on and at the logo screen I press and hold F2, this takes me to the InsydeH20 Setup Utility Screen. I see under the "Information" menu that the installed harddrive model and serial number appear. I see in the "Boot" menu, Boot Mode: "UEFI" and Secure Boot: "Enabled".
Under the "Exit" menu, Exit Saving Changes is highlighted. When I press F10 a "setup Configuration" box appears asking to save configuration changes and exit now? "Yes" is highlighted to which I hit Enter and are returned to the "Default Boot Device.......page. I then hit ecs twice and are at a black screen with the message No bootable device -- Please Restart system_appearing in the upper left corner of the screen. I then push and hold the power button until the computer shuts off.
I have ordered from acer the "Acer E-recovery Media Disc Set", which is specific to the SNID of my computer. I have not attempted to format the new hard drive in any way. I assume the E-recovery Media Disc Set will handle that operation due to the multiple partitions required.
In view of the above situation, do I need to set up the computer in any way before I start to utilize the E-recovery Media Disc set. I assume the Media will be on CD's. The computer was running Win 8.0 which was updated to Win 8.1 and was running very well, very stable.

I have an ao725-0687 netbook with windows 8.1 (from the factory). I wish to access UEFI (Bios). The method at [URL] {Accessing the UEFI (BIOS) setup on a Windows 8 / 8.1 system} does not work on my machine. My machine does NOT show the "UEFI Firmware Settings" button on the relevant page (but it DOES show the other 5 buttons shown in the video to be on that page). How can I access UEFI on this machine?

Machine is an Aspire 9301AWSMi running XP SP2 rather than Vista.
On boot, the machine shows the ACER BIOS screen but after that the display just goes blank. Have tried to boot from the Windows XP CD and the only difference is that following the BIOS screen I then get a message saying "Windows is inspecting your hardware configuration" and then a second or 2 later, back to a blank screen. No disc or CD activity.
Is this another ACER Motherboard problem or maybe a HDD failure?

After I turn on the power, the harddisk led doesn't turn on, just the CAP and NUM led flash once. The screen doesn't turn on, even the Acer logo doesn't appear. I can hear something is turning inside the notebook, but it's definitely not the harddisk.
I wonder if I had pressed some wrong buttons, and disable the notebook.

I have an acer aspire 1681wlmi which has just finished its extended 3 year warranty. The problem started by freezing upon start up on a white screen then the freeze up got quicker and quicker each time i rebooted it. Now the power on starts the hd, everything flashes like normal and after 5-6 seconds the hd stops and the hd light goes out. It wont boot from cd, it tries, the cd spins then everything goes dead again. I have tried all the previously mentioned fixes mentioned on this forum like removing battery, memory etc, i even tried to dismantle the whole thing but when it got down to the motherboard i did not want to break anything and put it back together again. I havea feeling the mother board is dead....
