Z77A-GD65 (mostly) unable to boot usb in legacy mode

So I already made a post about this issue over in the BIOS forum back when I assumed it was something to do with the forum flash tool, but upon closer examination I was able to replicate this problem with other bootable usb sticks when I attempted to boot them in legacy mode instead of UEFI mode (and while this is viable for the Windows 8 image usb it isn't for the flash tool since when I try to boot that drive in UEFI mode it hands off to the Windows bootloader).
I am not sure where I'm going wrong here (or where to start) because this behavior doesn't seem entirely consistent and I haven't recognized any pattern in which it occurs. Basically whenever I try to boot a bootable usb device from the efi boot menu in legacy usb mode I'm presented with a black screen with a blinking white cursor in the top left corner. The inconsistency that I describe is that every so often the usb will actually boot, sometimes after only a few seconds of the blinking cursor, sometimes after leaving the screen up for an hour or so, and sometimes even if I leave the screen up overnight it still will not boot (this is what happens the majority of the time, regardless of the time interval).
I've used the "fix my stick" option in the forum tool. I've used the HP utility. Since it can be replicated across multiple usb drives I am fairly certain it isn't a geometry issue and has got something to do with my bios settings or my usb controller itself (although the only other problem I've had regarding usb is my wifi adapter only working properly on a specific port and I believe that to be unrelated).
Obviously something is amiss here. Any settings I should check out? I'm currently running no OC and I'm trying to recover my BIOS A after something went awry with the flash tool (long story as to why I was flashing in the first place, not really worth going through unless prompted...but this issue has been going on since at least early january).

I did have some issues with the ME fw at the beginning of January after a bad M-flash, but I thought I had recovered. After seeing someone with a similar problem (but with more symptoms of bad usb) had success with booting from usb after disabling the sata controller temporarily. So I've been doing that and it seems to work for now, even if it is kind of a roundabout way.

Z77A-GD65 - Problems installing Windows 8.1 in UEFI mode

Hey guys.
I've got my new Samsung 840 Pro SSD today and I want to install Windows in UEFI.
So I got a 32GB USB Sandisk drive, I formatted it to FAT32 and used WinUSB maker to make it boot from a Windows 8.1 ISO file.
I went into BIOS and selected UEFI boot mode, and set UEFI: USB Hard Disk as the first boot option.
That didn't work so I tried UEFI: USB Key which did the same.
Unfortunately I'm not able to boot into the installation. I can only boot to the MSI UEFI Shell and I have no idea what to do from there.
I tried clicking F11 to get to the boot menu but I only have "UEFI Shell" and "Enter Setup" to choose from.
For some reason neither my USB drive or my Samsung 840 Pro are recognized in UEFI mode at the Boot menu.
I plugged in the USB drive to my laptop and verified that the file system is indeed FAT32 and not NTFS.
Maybe it's because I used WinUSB maker?
Please tell me what to do because I really want to install 8.1 in UEFI.
Thanks

I had this same problem with trying to install Windows 8.1 from the ISO I was able to download from MS. I eventually got the installer to work. Two ways to do this.
1. Set your BIOS boot option to Legacy + UEFI
2. Change your boot device to the legacy form of your USB flash drive
That should make it boot.
or
1. While at the shell command prompt
2. Shell> Fs0:
3. fs0:> \EFI\BOOT\BOOTX64.EFI
Or type whatever the Flash device is labeled as
Hope this helps,
I have the Z87-GD65 mobo but I imagine the Z77 has a similar bios...

Unable to boot normal, in safe mode or from install DVD

When I walked into my office this morning and hit my keyboard to wake my Mac all I saw on the screen was a white mouse arrow and a black screen. I held down the power button to restart, it starts to boot and then stops at a gray screen telling me to hold down the power button and restart. Doing this brings me to the same screen. I have attempted the following:
Booting while holding the Shift key - this takes a bit longer but takes me to the same gray screen
Booting with the install DVD in and holding the "c" key - DVD spins a bit then gray screen
Booting while holding "option" and selecting the install DVD - DVD spins a bit then gray screen
Booting in Single User mode and ran "/sbin/fsck -fy" it returned - *** FILE SYSTEM WAS MODIFIED ***, ran it again and returned - ** The volume Macintosh HD appears to be OK
I am not sure where to go from here, and advice would be much appreciated.
Thanks,
Bob

I posted in the wrong forum, I am using 10.5, I have reposted this in that forum.

Z77A-GD65 Error 55 constant boot loop

I'm very confident the Board itself is dead. I tried all the usual suspects one stick of ram, CMOS reset etc. etc. finally resorting to replacing the motherboard with an old Z68A GD65 which booted faultlessly first time. Just confused why the board would suddenly report an error like this after running faultlessly and with no changes to the bios or the PC itself since I bought the unit it was flashed some months ago to the latest bios version with no problems. I need to check if I can RMA the board but is it really worth the time?

Well, if board doesn't work while another board works with all the other components it is pretty surely faulty. Of course you can then go for rma.
In Europe that takes contacting reseller.

Leopard Unable To Boot, Loops In Verbose Mode

Hi everyone,
I really hope someone can help me out here!
I recently backedup(Leopard), partitioned(my internal HDD) and restored Leopard
but now when booting it just stalls at the Apple screen with the loadnig circle at the bottom. I have done resores numerous times before and this is the first problem i have had.
No matter how long I leave it loading (+5 hours, to test) it never loads.
It doesnt start in safe mode, single user mode and when in Verbose mode it infinetly loops at this portion:

I have a small backup partition of Tiger and it workd fine, i can see the resored drive and all its contents(Applications etc.) and disk utility reports no problems when verify and repairing the disk.
I have also run Hardware diagnostics at startup and it reported no errors.
Any help you can offer would be greatly appreciated as I do not want to loose Leopard and all my files.
Thanks.

See if you can boot into the Leopard DVD. Insert DVD, reboot and hold down "C" key.
After language screen, in menu top left under Utilities, you will find disk utility.app (DU)
Run DU and first verify/repair HD and then repair permissions on the Leopard volume.
Reboot and see what happens or report back with any problems or errors you get.
Also, since one backup is SuperDuper! can you boot into that? Hold down Option key on boot and see if it shows up. If it does, does it boot normally?

Yoga 11s - how to boot from USB in UEFI mode (tried everything)

I have been trying for days to install Windows 7 on my new Yoga 11s in dual boot configuration with 8.1, with no luck. Typical catch-22 problem -- can't boot from the install media in UEFI mode, and if booted in legacy mode, Windows won't install on GPT partition. I followed all the steps everywhere mentioned: disabled secure boot, set boot mode and order in every possible combination, etc. I followed these steps exactly to create a UEFI-bootable USB drive:http://forums.lenovo.com/t5/Windows-8-and-8-1-Knowledge-Base/Why-can-t-I-boot-from-a-USB-key-on-UEFI-ThinkPad-or-ThinkCentre/ta-p/1004621 I can boot easily from the USB in legacy mode, but in UEFI mode, when starting the machine, the USB is ignored. If I go into Windows 8.1 recovery and do an advanced start and choose EFI USB, the machine thinks for a moment and then says: "System doesn't have any USB boot option. Please select other boot option in Boot Manager Menu." Then I click OK and it offers only one option on the menu, Windows Boot Manager. I don't know if the lack of boot options is just a symptom of the USB not really being UEFI-bootable, or some other steps are needed to add boot options. I even tried adding an item within the windows boot manager, but that didn't work, because even if it could work in principle I don't know the right settings. Has anyone actually made this work? If so, what is the secret?

I had the same problem and a lot of frustration. I finally solved the problem by using a different USB key. I also had to go into boot options and select the USB key even though I had the USB key first in the boot order. Right now I am Re-imaging from my backup and pray for success. Although things may look brigth afterall I have to leave out some steam:The whole problem started with a screen error, which had to be repaired. So before sending it to repair I made an image backup, - just in case. I got an eight hour time window where I had to wait for a pickup of the computer,- very frustrating when you are having a job requiring traveling. After ten days the computer computer came back with a scrambled hard disk with at note saying that it was an software error, although it was no doubt an hardware error because it worked perfectly with an external monitor. I have not counted the number of hours this bad service has costs but it exceeds the value of the computer!

Varying boot times - Z77A-GD65

I have a new build and find that the boot times seem to vary for no apparent reason. Most of the time I will see the MSI splash screen within 15 seconds and then it boots quickly into windows. However, some times it will hang up on codes A2, B4, C3, or CA for up to 45 seconds before the splash screen appears and then it boots fine. I will note that no matter how long the boot takes, the system runs flawlessly and has never crashed or had any odd behavior other than the varying boot times. I see from the manual that A2 and B4 are Onboard Devices Initialize and Detect, but this happens randomly without changing any of the onboard devices. I ran memtest86 on the ram for over 12 hours and 6 passes and got no errors.
Anyone else have this experience or any suggestions on what may be causing it? I'm OK with it if others have the same experience and it is normal. I'm just concerned that it is a sign of some sort of problem.
First post, thanks in advance.
Intel i5-3570K (stock speeds)
MSI Z77A-GD65 board
Seasonic M12II 750 w psu
Corsair Vengeance LP Ram (16 GB)
Samsung Pro 840 128GB SSD drive (boot drive)
WD Caviar Black 500 GB HDD (data drive)
Win 7 Pro
ATI Firepro V5800 graphics
Noctua NH-U12P SE2 heatsink
Corsair Obsidian 550D Case

I tried disabling the PCIE GEN3 and I don't think it helped. I did a few restarts and still got a hang up on CA, whatever that is. Thanks for the codes. The most common ones I get seem to be:
A2 - IDE Detect
B2 - Legacy Option ROM initialization
B4 - USB Hot plug
C3 or C6 - OEM BDS Initialization Code
CA - no idea
The strangest thing is that I would say 7 out of 10 times it starts up perfect. The other 3 it will hang on something, but then it still boots and runs perfect. It just strikes me odd that I can make no changes whatsoever and it can go from perfect to hanging up. If anyone has any other suggestions for any of those codes, please feel free to respond. Thanks.

Z77A-GD65 Unable to reach BIOS setup

Motherboard: Z77A-GD65
CPU: i5-3570K
GPU: EVGA GeForce GTX 660Ti
Memory: G.SKILL 8GB, 2x8GB, 1600MHz
SSD: Intel 330 Series 2.5-Inch
Bios A: A.A
Bios B: A.A
I am dual-booting Windows 7 and Mac. At some point along the way of getting this set up, I have seemingly broken access to my MSI BIOS.
My computer is able to boot into Windows 7 and Mac no problem, and is completely functional in both partitions. But I am completely unable to access my BIOS setup screens (using the DEL key during startup).
When attempting to access the BIOS during startup, I hit the DEL key and it flashes briefly on the BIOS screen (blue MSI logo, but most of the controls are not rendered, the UI looks corrupted) before restarting immediately.
I have tried many times to flash the BIOS to various versions, including the prior 3 versions before A.A and have been unable to reach the BIOS screen.
My most recent BIOS flash was using the Forum HQ tool, and I installed the Intel Management Extensions afterward.
While my computer is functional, I am worried that eventually I will need access to the BIOS to change or update settings and don't like not having this capability. Does anyone have any idea how to get back to a working BIOS? Has anyone seen the problem where the BIOS screen partially renders but then goes immediately into a reboot?
Any help would be appreciated -- apologies if I have omitted any important details. Let me know if more background would help.
Thanks,
Josh

Hi Svet, thanks for the advice. I tried to use the GO2BIOS button which essentially caused the same outcome as when I jam on the delete key during restart.
Basically, it initiates a reboot, the black startup screen begins...
1) I see 9C in the lower right corner
2) then B4 for several seconds
3) then very briefly A2.
4) Then the blue BIOS screen flickers in the upper-left corner (btw, this is only a partially rendered screen, it's only the title bar plus the boot dropdown which is unclickable), then the computer restarts and goes back to step 1.
I also have tried using the ClickBIOS and that just fails to start with an error like "SCEWIN_64.exe has stopped working".
I think my issue is deeper, any further ideas?
Thanks,
Josh

Z77A-GD65 Win7 64bit boot fail followingMSI Live Update 5 Firmware update

Hi,
For some reason I decided to have a go with MSI Live Update 5 auto update today (having not used it previously in the 1.5years I've owned this system.
Running in Win 7 64 bit, it performed an 'update' and then the system completely crashed (as in turned off and on again). On reboot the system only went as far as the BIOS flash screen.
It failed to boot form the SSD boot drive and a message saying "Reboot with Proper Boot Drive".
I booted into BIOS (version 10.11) and the boot drive is still recognised.
I tried a reboot and the same error.
I tried to boot backup within BIOS and saw a message flash that ended with "Failed to initialize MSI-X".
None of the MSI applications work, it doesn't boot into Windows and I'm stuck.
Can anyone suggest how I might be able to get Windows back and running without having to do a full reinstall? I can't seem to get the backup software to work now so I'm a bit stuck. If I try and do a full flash of the drive and start again, will it fix the issue or is the problem with the motherboard/bios setup?
Has anyone else had this problem?
System spec:
MSI Z77A-GD65
Intel i7-3770k 3.5Ghz
Corsair Vengeance LP 8GB RAM
Win7 64Bit

YES
OK, so I found a few people on Tom's Hardware message board that seem to have the same issue with this latest BIOS update from MSI so at least it's not just me.
I reset CMOS
I set BIOS to default
I downloaded the BIOS ME from an older version 10.8 of BIOS that I knew worked fine (from another computer)
Flashed BIOS with USB
Booted the system with Win7 64 OEM CD
Selected Repair Mode
Let it do its thing
I'm back in business from where I left off.
Won't be touching the BIOS update again unless I can be absolutely sure its going to be stable on my MB.
RE: Legacy and UEFI
After installing 10.11, it defaulted to UEFI only but I changed the setting to Legacy and UEFI. It didn't fix the issue though.
I've rolled back, it works again so I'm happy other than the fact I've lost almost a full day of work over it.
Cheers xmad

Z77A-GD65 + Samsung 840 Pro Slow Windows 8.1 Boot time?

Hey guys,
I've recently installed Windows 8.1 in UEFI mode on my new Samsung 840 Pro drive.
However, just for fun I started testing my boot time.
From the moment I press the Power button I'm in Windows after 25 seconds, it seems to hang on the A2 code for about 6-8 seconds every time, however, not on restart.
A restart is much faster and only takes about 10-12 seconds.
However, I was looking in Youtube and most guys there boot their PC with inferior SSDs than mine in about 15-18 tops.
I was just wondering if a 25 seconds boot time for the fastest SSD today is considered normal?
Also, is it related to my CPU? I'm using a 2500K, I assume most of the videos I saw were of people with Ivy/Haswell bridge CPUs.
In my BIOS I am using the Windows 8 features and "Fast Boot" is enabled, "Secure Boot" is disabled.
Thanks
EDIT
Found the issue! Turns out my new WD 3TB Caviar Black drive is causing the hang. I disconnected it and my PC booted within 12 seconds since I pressed the power button.
I have the 3TB drive connected to a SATA3 port on my Intel controller.
Any thoughts?

I had this same problem with trying to install Windows 8.1 from the ISO I was able to download from MS. I eventually got the installer to work. Two ways to do this.
1. Set your BIOS boot option to Legacy + UEFI
2. Change your boot device to the legacy form of your USB flash drive
That should make it boot.
or
1. While at the shell command prompt
2. Shell> Fs0:
3. fs0:> \EFI\BOOT\BOOTX64.EFI
Or type whatever the Flash device is labeled as
Hope this helps,
I have the Z87-GD65 mobo but I imagine the Z77 has a similar bios...

Boot issue with Z77A-GD65

I have a Z77A-GD65 board with 16GB of DDR3 RAM (4x4GB DIMMS) and an I5 Ivy Bridge CPU, Samsung 830 128GB SSD and 2x 4TB HDD's.
Last night my system was working perfectly. Today it won't boot into an OS.
When I would power up the system this morning, it started went through the Intel Matrix RAID BIOS fine then did a few status codes in the bottom right and ended up on A2 as the current code and sat there forever... I let it set for 15 minutes about no change.
I pulled the HDD's and SSD off first, same code
I pulled the USB and ethernet now the code changed to D0 still nothing, just hangs there.
I switched the BIOS switch to the second one, same result.
I pulled the BIOS battery and power and let it sit for a while, plugged it back in and put the battery back in... same result..
What's going on? I'm not sure where to go nor do I know the exact meaning of the codes given

Quote from: Svet on 15-September-14, 23:25:51
what is your bios version?
The BIOS that went nuts was A.B0, I did get it to boot though, just not with that BIOS...
I pulled all the cards, all the memory, anything plugged in HDD/SDD etc.. only thing left was onboard DVI and keyboard... cleared the CMOS again with the back button and it went into a never ending reboot loop.... switched it to the second bios via the switch on the motherboard, cleared the CMOS again, and bingo it booted... I think that BIOS 1 is corrupt... not sure what caused it, haven't done any updates or anything since A.B0 came out. And haven't made any hardware changes in that time either... worked great until this morning turned it on and boom It was stuck at A2 on the BIOS startup.
My question now is, how do I reflash BIOS 1? I read somewhere before I think that I have to do a multi bios update, but not sure how to go about doing that.

Z77a-gd65 stuck at boot?

Hey there, I have a z77a-gd65, I run the v10.0 bios on bios 1, I switched to bios2, and used the msi flashing tool usb thing on here on the forums and the v10.11 I think, 7751vAB.zip to be exact, and it flashed fine, all went well, can enter bios settings etc etc.. but then when it gets to booting phase, it hangs (led screen on mobo shows 38, no idea what that means), and it just sits there. and I tried disabling all booting options and set my Samsung evo 840 as the boot where I have windows installed, it hung for maybe 30 seconds then said insert proper boot media like it would if there was no data on the drive, so I panicked and switched to bios 1.. all is working well nothings changed at all.
So it must be something to do with the latest bios update?
I have a 2500k, z77a-gd65, 16gb corsair xms.
I did all the steps and guides id found, bios 2 was default at flash infact id never used bios 2 ever, but it booted fine etc, also this board is only 3 months old if less, but I just wanted to see if anything was new in the new bios.
So what do I do with bios 2 now?
Thanks!

iv fixed it, I updated to 10.8 bios and it boots, wouldn't boot with 10.10 or 10.11 though.
In this bios, I cant changed my cpu multiplyer on the standard settings though, I have to use the rubbish oc genie to overclock? and under load, before I used 4.5ghz 45x multiplyer. Im at that using the genie custom settings, but under load it drops to 44x for some reason, any idea why?

[SOLVED] Unable to boot ISO on USB

Hello,
I'm unable to boot from USB. I have the following error : "Failed to install override security policy: (14) Not Found".
I tried the following solution : http://superuser.com/a/676059
But then my computer does not want to boot on the USB. I don't have any option for UEFI on my computer's BIOS (ASUS eeepc). Note that I don't want a dual boot with Windows and there is currently a broken archlinux installation on my hard drive.
Can anyone help me with this ?
Thanks. :-)

Yes, I used :

And for creating the ISO (after copying the file for the workaround) :
genisoimage -iso-level 4 -o archlinux.iso archlinux

This may be caused by buggy uefi firmware, check if there is a new one for your card.
Also in some cases it can be caused by fastboot/similar so check for that too in the bios.
I don't have an option for last boot. I'll check for a new uefi firmware !
EDIT: How do I check for that ?
I have an option on the BIOS "Launch EFIT Shell from filesystem" which search for Shellx64.efi on the available filesystem devices. However, it is calle shellx64_v1.efi and shellx64_v2.efi on the archlinux iso. May be this be a problem ?
Anyway, it's strange, the last time I installed Archlinux this eeepc (more than one year ago...) I didn't had any problem !
