Problem booting from Acer Aspire?

  • SpinRite v6.1 Release #3
    Guest:
    The 3rd release of SpinRite v6.1 is published and may be obtained by all SpinRite v6.0 owners at the SpinRite v6.1 Pre-Release page. (SpinRite will shortly be officially updated to v6.1 so this page will be renamed.) The primary new feature, and the reason for this release, was the discovery of memory problems in some systems that were affecting SpinRite's operation. So SpinRite now incorporates a built-in test of the system's memory. For the full story, please see this page in the "Pre-Release Announcements & Feedback" forum.

  • BootAble – FreeDOS boot testing freeware

    To obtain direct, low-level access to a system's mass storage drives, SpinRite runs under a GRC-customized version of FreeDOS which has been modified to add compatibility with all file systems. In order to run SpinRite it must first be possible to boot FreeDOS.

    GRC's “BootAble” freeware allows anyone to easily create BIOS-bootable media in order to workout and confirm the details of getting a machine to boot FreeDOS through a BIOS. Once the means of doing that has been determined, the media created by SpinRite can be booted and run in the same way.

    The participants here, who have taken the time to share their knowledge and experience, their successes and some frustrations with booting their computers into FreeDOS, have created a valuable knowledgebase which will benefit everyone who follows.

    You may click on the image to the right to obtain your own copy of BootAble. Then use the knowledge and experience documented here to boot your computer(s) into FreeDOS. And please do not hesitate to ask questions – nowhere else can better answers be found.

    (You may permanently close this reminder with the 'X' in the upper right.)

My laptop is a V5-171 mfg date 2012/09/06 (replaced HD with SSD).

F12 for boot menu only showed Windows boot manager until I changed BIOS (F2) boot setting from UEFI to Legacy.
At that point I could boot & use the ReadSpeed USB stick (but could not boot HD until I restored boot setting).

Next step - get upgraded Spinrite!
 
My Acer Aspire is a desktop TC-895. I cannot change from UEFI in the BIOS. I have tried to disable Secure Boot, turning off TPM, disabling all drives but the Removable, disconnecting all external drives and peripherals. I cannot seem to get the machine to boot from USB. (My BIOS is Del, FWIW).

I've been there with my Surface Book. If you don't have legacy boot and can only boot into UEFI, you are out of luck. Turning off secure boot or TPM won't help. Once @Steve updates SpinRite to support UEFI instead of BIOS, you will be good to go.
 
I have a similar problem with an Acer Aspire 5 laptop; I have the BIOS set to boot from USB. It will boot to a Kubuntu USB, is running Kubuntu. The Readspead USB will boot and run on my Win desktop but the RS USB isn't seen in the laptop BIOS....

What is the F2 menu? Is that the boot choice menu? If so, it wouldn't let you change to something else if the BIOS settings aren't appropriate. On the other hand, why would they even show what type of boot they allow, if there is no chance to change it. Get into your BIOS and look for the key phrases: legacy boot, CSM, secure boot. In particular for a legacy OS to boot, it would need the CSM (Compatibility Support Module) to provide the functionality that (for SpinRite) FreeDOS relies upon.

WARNING: If you use Windows boot encryption and/or BitLocker, MAKE SURE YOU HAVE BITLOCKER KEY BACKUPS. Messing with disabling Secure Boot can initialize your TPM and erase the BitLocker keys.

There is no standard for these things. So when you talk about the F2 menu we don't know what that means. If the ACER Aspire 5 is a relatively new machine, then it's more likely that it won't be able to boot DOS. Your best best would be to search the Net to see what you can learn. As Paul Holder noted, phrases like "legacy boot" or "CSM" would mean that the machine CAN boot a BIOS-based operating system.

Note, also, that GRC's newest freeware, "BootAble" allows you to experiment with this before you commit to a SpinRite purchase.

Yikes, Paul... do we have evidence of this? Is it the case that enabling/disabling Secure Boot will erase Bitlocker keys?

@fibar above appears to be booting his Acer Aspire 5 in BIOS mode. I suggest you go into System Setup and look at the BIOS settings for a CSM option.

ReadSpeed has its own drivers to see and access internal drives. ReadSpeed does NOT have USB drivers and does NOT use the BIOS, so external USB drives are invisible to ReadSpead.

It's a ACER Aspire 5 A515-56 which does UEFI boot. I did see a procedure in the Acer forums for a A515-44 but that looks too risky to me as if I change the boot method as there is a warning that ONLY MBR/Legacy formatted drives will be recognized if the laptop was changed to legacy boot. I can try the BootAble utility but suspect I will have to wait until SpinRite supports UEFI boot. I've read the GRC Development Roadmap so can see support of UEFI is on the way.

It may not have any CSM/legacy boot option. The only way to know is to go into the System Setup and see what's there.

Note: We are NOT talking about a permanent boot change here - only a temporary one - if it is possible.

That is . .

Change to CSM/Legacy boot (if possible)
Boot and run SpinRite 6.1
Change back to UEFI boot when done

It ought to be straightforward.

Yes SpinRite 7.0 will be UEFI/BIOS dual bootable! :)
