BootCD would not boot my B&W; something about a video driver. Here's a solution that works every time - even from OSX:1. Use Apple's Disk Copy (in OSX) and create an image from the OS9 CD. Make sure you specify "CD/DVD master" from the popup menu or it will not be bootable.2. Mount the image and toss out the junk you won't need (like the installer stuff).3. Drag over items like your Norton SystemWorks folder (making sure that the Norton SharedLib file is inside the Norton Tools folder - you can find it in your Extensions folder).4. Unmount the image.5. Use Disk Copy to burn the image back to a CD.*presto*
I make tons of bootable disk using just read/write format from disk copy. They work fine, bootable, modifiable, etc!! I have not tried to make an OS X bootable. The sad part of OS X is that OS 9 is much easier to deal with when there are serious hardware issues. Mostly because there are a lot more options for utiliies under 9, that have had years of development.
DiskWarrior 44 Bootable DVD Mac OSX
...the reason you can't make an OS9 bootable CD with Toast under OSX is that it won't. Doesn't support it under OS9. Roxio says reboot into OS9, launch the app and it will work unless something has changed in the last month.. You can do it with Disc Copy copying the system folder to an image and using the bless -system9 command in the Terminal.
I have a CD that boots in OS 9 with my diagnostic utilities. I use this CD on client's Macs, so I like to keep the latest system and application updates on it. I created this CD in OS X. About once a month I make changes to the contents of the CD's disk image and burn a new CD. I did all this without using Toast or any terminal tricks. Here's how:In OS X, mount a bootable OS 9 CD.Open Disk Copy.In the Image menu, select New Image from Device.Select the CD.Name the image, and use the CD/DVD Master format when saving the image file.Eject the CD.Now you can open the image file, rename it, and add or remove any files or apps you want. When you "eject" the image, the changes will be saved.To burn the image file to a disk, open Disk Copy again.In the Image menu, select Burn Image.Select your image file, and pop in a blank CD.
If everything fails, the only option left is to use a data recovery application which can scan and recover as much data as possible. Disk Warrior 4 is one such application which saved the day for me. You can either use a bootable DVD or create a bootable USB as shown below.
Got this useful repair invalid b tree node article while web search. It uses a volume optimizer software to repair a severly corrupt Macintosh HD. But to work on the OS X drive, one needs to create a bootable media makeing the Macintosh HD as secondary disk drive. This could be helpful if disk is badly damaged and no tips are helpful.
EaseUS Data Recovery for Mac is a modern data recovery solution that can recover up to 2 GB of deleted and formatted data for free. It supports Time Machine backup drives, recovers photos, videos, music, documents, and emails, and works with all recent versions of macOS, including macOS 10.14, 10.13, 10.12, OS X 10.11, 10.10, 10.9, 10.8, 10.7, and 10.6. Data recovery with EaseUS Data Recovery Wizard for Mac is a three-step process, and the app even lets you create a bootable media to recover data when macOS is unable to boot up.
My computer crashed and damaged directory files on my external hard drive. So it wouldn't mount but I could see it in Disk Utility (altho it wouldn't repair). Paid the $120 for the diskwarrior, went thru everything and it was fine. Gives you a preview to grab files too before they go in and fix the bug. Worth the money.
As far as I know, the only way to properly create a bootable Lion disc/disk is to use Disk Utility on a working Mac. However, the other option is to use a Virtualbox VM to run OS X temporarily (scroll down for that info).
Hit the Options button under the partition table and choose "GUID Partition Table". You'll need this to make the drive bootable on a Mac. Hit the Apply button when you're done to format your drive (note: it will erase everything on the drive).
I have a Mac Air gifted by son. I am almost a dummy, with only very limited proficiency in mac. Son upgraded the OS to Lion free as it was allowed. It is running OK. Do I still have to spend USD 30/- to make a bootable USB stick. Is there any other method to make Boot USB key or MicroSD via USB reader for a dummy like me.
If you open App Store and click Updates, you can update your Lion installer to version 1.0.16. It replaces your copy if you allowed it to self-erase at installation. But using the InstallESD.dmg from inside this installer (SHA1 = 8ef208772f878698e9dd92b3632e25b23ffc9ca7) creates a bootable 10.7.3 (11D50) USB stick. That is cool.
Is this bootable Lion image something that you can use as an emergency repair disk by adding things like DiskWarrior and TechTools Pro (when they are lion certified)? Or is this bootable image only capable of booting and installing Lion?
after around 50 hours, diskwarrior gave me my drive back, with all the files intact. it ended up with 1961 overlapped files. i guess i was lucky, but from now on i will make sure i have a copy the diskwarrior cd with me wherever i go. i love this program!
As my External drive was previously bootable on a pc ( which I checked before starting disk warrior 10 days ago) I am thinking to maybe cancel disk warrior try booting on the pc and connecting another drive to copy the files over. Do you think this would work ?
Diskwarrior 5 stuck in Step 6 for almost 1 week (6 day and 15 hours) and after detecting over 55k overlapped files. Then I view the report, and click the replace. It quickly goes to Step 12 of 12 repairing overlapped file. there was no progress on diskwarrior progress bar to tell how many overlapped file is fixed. This step 12 stuck for another 5 days, then it give me the following error:
At this point, fsck_hfs verification has NO error anymore. TimeMachine backup verification also passed. but I am still not sure, so let diskwarrior5 do another rebuild. this time it finished in 30 minute and replace take about 5 minute only. No overlapped file detected anymore.
That extracted OS9Genreal DMG has been invaluable. I struggled for 3 days to figure out why every boot disk I downloaded, including the original machine disks, simply would not turn into bootable OS installation volumes.
In 10.15 Catalina, Apple introduced APFS volume groups, a way of bundling separate volumes together to create a bootable macOS. A System volume holds all the files macOS needs to operate, while the Data volume contains only your data. The two volumes appear as a single entity in the Finder and wherever you might select or navigate files. The System volume is also read-only, so malicious software cannot modify the operating system, whereas the Data volume that contains your files remains read-write so you can install apps and create and modify documents.
All this is to suggest that the bootable part of a bootable duplicate is no longer as essential for many people as it was when we first started recommending that a comprehensive backup strategy should include one. Since then, it has become far more common for people to have multiple devices on which they could accomplish their work, and much more of that work takes place in the cloud or on a remote server.
What do you think? How often have you relied on a bootable duplicate to return to work quickly after an internal drive failure? Have you been stressing about bootable duplicates in Big Sur? How would you respond to your Mac failing entirely?
Quick recovery: The primary reason for having an up-to-date bootable duplicate is so you can get back to work as quickly as possible should your internal drive fail. Simply reboot your Mac with the Option key down at startup, select the bootable duplicate, and continue with your work. If your Mac were to die entirely, you could use the clone with another Mac you own or borrow, or a replacement that you can purchase and return within 14 days.
I booted the system from my emergency recovery partition (I had previously created a second partition with a minimal Mac OS X installation that contained the OS, Retrospect, Disk Warrior and little else) and used Retrospect to restore my system and data partitions. (I also had a bootable DVD for use in case both hard drives died at once, but I never needed to use it.)
Excellent article and questions/solutions!I come from the Oldskool of having an active, weekly, silent clone to an spinner (on internal bus, for speed) along with no longer supported TM Airport (modded for 4TB). You.Can.Not.Have.Enough.Backed up. I even considered buying a cloud sub to carbonite/code42/AWS container or other service but none are one-stop-one-deal. Having a bootable clone (if daily), allows you to fumble with some update and screw the pooch, and boot back to last time, phew.I wonder, if you have a T-bolt mac enabled, can CCC clone to that mac partition so you have a daily driver ready, that is only tethered via Tbolt 3 cable? Is that doable?I just ordered a T7 drive to use for cloning macs as I also migrate (just incase). But I also wonder, we are coming to full circle in that, its all in the cloud. Terminal/server will be i-device to login, run your desktop on a display with gig connection. Local is for emergencies only (like power outtage).I think we need to get internet access as a regulated utility!
I have a specific reason to ensure I have a bootable SSD backup, apart from the obvious. I have a beautiful late 2014 27" 5k iMac. I know that SSDs have a limited life, and the internal 500GB SSD is now over 6 years old. I have been getting the occasional odd behaviour and therefore I have numerous backups scheduled daily via CCC. However, the internal SSD is going to fail someday, and is probably not financially worth trying to get it replaced. But the 5k 27" screen is still magnificent! So I will be able to use my Samsung T5 SSD as my primary drive and keep all my systems and the iMac screen running normally! 2ff7e9595c
