        "content": "If you're having trouble booting from USB on a new Lenovo ThinkPad, there are a few common causes. We\u2019ll go through what to check and what to try. If you tell me your exact model, I can get more specific steps.\n\n---\n\n## Common Reasons USB Boot Fails on New ThinkPads\n\n1. **Secure Boot is enabled**  \n   Secure Boot is a security feature that ensures only software signed by trusted providers (like Microsoft or Lenovo) can load during startup. If your bootable USB is not signed or built for Secure Boot, the system may reject it. ([download.lenovo.com](https://download.lenovo.com/pccbbs/mobiles_pdf/lenovo_thinkpad_x250_bios_security_white_paper.pdf?utm_source=openai))\n\n2. **Boot mode locked to UEFI only; Legacy/CSM is disabled or greyed out**  \n   Many newer ThinkPads ship with UEFI-only booting, with Legacy BIOS/CSM disabled. That makes it tough to use certain USBs, especially ones built for Legacy mode. Sometimes the option to change to Legacy is simply unavailable. ([pubs.lenovo.com](https://pubs.lenovo.com/uefi_amd_4th/legacy_bios?utm_source=openai))\n\n3. **USB drive not properly formatted or not bootable**  \n   The drive needs proper format (often FAT32 for UEFI) and must contain a valid bootloader compatible with the machine\u2019s firmware. If the USB was made using a wrong mode (e.g. NTFS only, wrong partition table, wrong UEFI vs Legacy setup), the firmware might not recognize it. ([download.lenovo.com](https://download.lenovo.com/pccbbs/mobiles_pdf/p1_g8_t1g_g8_ug_en.pdf?utm_source=openai))\n\n4. **Model or firmware limitations/restrictions**  \n   Some newer ThinkPad models have manufacturer-imposed restrictions\u2014BIOS options locked down, Secure Boot defaults that only show approved keys, disabled Legacy support, etc. If the laptop is corporate-owned, there may be overrides. ([iknow.lenovo.com.cn](https://iknow.lenovo.com.cn/detail/183463?utm_source=openai))\n\n5. **Wrong USB port or bad connection**  \n   Occasionally the port you use matters (USB-A vs USB-C, front vs back). Also possible: the USB drive itself is failing or only partially formatted. ([download.lenovo.com](https://download.lenovo.com/pccbbs/mobiles_pdf/p1_g8_t1g_g8_ug_en.pdf?utm_source=openai))\n\n---\n\n## What to Check & Try\n\nHere are the steps you can go through one by one:\n\n| Step | What to Do |\n|------|-------------|\n| 1. Enter BIOS/UEFI settings | Boot the ThinkPad, press **F1** (or Fn+F1 if configured) as soon as the logo appears. ([download.lenovo.com](https://download.lenovo.com/pccbbs/mobiles_pdf/p1_g8_t1g_g8_ug_en.pdf?utm_source=openai)) |\n| 2. Check Secure Boot setting | Navigate to *Security \u2192 Secure Boot*. If Secure Boot is **Enabled**, try disabling it. If disabled, but boot\u2019s still failing, look for \u201cAllow Microsoft 3rd-party UEFI CA\u201d and enable that. ([download.lenovo.com](https://download.lenovo.com/pccbbs/mobiles_pdf/Enable_Secure_Boot_for_Linux_Secured-core_PCs.pdf?utm_source=openai)) |\n| 3. Check boot priority and boot mode | Go to *Startup* or *Boot*. See if \u201cUSB HDD\u201d, \u201cUSB FDD\u201d, or your USB device appears in the boot-order list. If \u201cLegacy Support\u201d or \u201cCSM\u201d is needed, check whether those can be enabled. ([download.lenovo.com](https://download.lenovo.com/pccbbs/mobiles_pdf/p1_g8_t1g_g8_ug_en.pdf?utm_source=openai)) |\n| 4. Format USB properly | If using UEFI, reformat USB drive to FAT32, use GPT partitioning, make sure the installer image is UEFI-compatible. If firmware expects legacy, use MBR + NTFS or another correct format. ([download.lenovo.com](https://download.lenovo.com/pccbbs/mobiles_pdf/p1_g8_t1g_g8_ug_en.pdf?utm_source=openai)) |\n| 5. Use the correct boot menu key | Turn on or restart, press **F12** (or sometimes Fn+F12) right at the Lenovo logo to bring up the boot menu. Choose your USB from there. Make sure the USB is plugged in *before* entering the boot menu. ([pcsupport.lenovo.com](https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-edge-laptops/thinkpad-e595-type-20nf/solutions/ht500207?utm_source=openai)) |\n| 6. Update BIOS/Firmware | If your BIOS is out of date, there may be bugs or locked features affecting USB boot. Lenovo support sometimes releases updates for this. |\n\n---\n\n## Specific Gotchas for ThinkPads\n\n- On many newer ThinkPads, once Secure Boot is enabled, Legacy support and USB boot options can be locked or greyed out. That means unless you disable Secure Boot or use a USB that's properly signed, you might be stuck. ([iknow.lenovo.com.cn](https://iknow.lenovo.com.cn/detail/183463?utm_source=openai))  \n- Some ThinkPads need \u201cAllow Microsoft 3rd-party UEFI CA\u201d enabled in order to boot Linux or non-OEM OS installers without disabling Secure Boot. ([download.lenovo.com](https://download.lenovo.com/pccbbs/mobiles_pdf/Enable_Secure_Boot_for_Linux_Secured-core_PCs.pdf?utm_source=openai))  \n- Changing boot mode (UEFI vs Legacy), disabling Secure Boot, or switching SATA mode (e.g., RAID to AHCI) **may** cause your current OS not to boot unless you prepare for it. If you rely on BitLocker or have encrypted disks, changing these can trigger recovery requirements. ([download.lenovo.com](https://download.lenovo.com/pccbbs/mobiles_pdf/p1_g8_t1g_g8_ug_en.pdf?utm_source=openai))\n\n---\n\nIf you tell me your ThinkPad\u2019s exact model (for example \u201cT14 Gen 5\u201d or \u201cX1 Carbon 2023\u201d), I can pull up steps geared to *your specific machine*. Do you want me to do that?"

        "content": "Here are the **specific steps** and settings to check for your **ThinkPad X9-15p Gen 1 Aura Edition** so you can successfully boot from a USB drive. These are pulled from Lenovo\u2019s own documentation as well as verified community insights.([download.lenovo.com](https://download.lenovo.com/pccbbs/mobiles_pdf/tp_x9_15p_gen1_ug_en.pdf?utm_source=openai))\n\n---\n\n## What you need to check in the BIOS/UEFI\n\n1. *Access BIOS Setup*  \n   Restart the laptop. When you see the ThinkPad logo, press **F1** (or press Fn+F1 depending on your keyboard settings) to enter UEFI/BIOS setup.([download.lenovo.com](https://download.lenovo.com/pccbbs/mobiles_pdf/tp_x9_15p_gen1_ug_en.pdf?utm_source=openai))\n\n2. *Disable (or adjust) Secure Boot*  \n   Go to **Security \u2192 Secure Boot**. There's a switch you can use to toggle Secure Boot on or off. If Secure Boot is enabled and you\u2019re using a USB installer that isn\u2019t signed/approved by the factory keys, it might be refused.([download.lenovo.com](https://download.lenovo.com/pccbbs/mobiles_pdf/tp_x9_15p_gen1_ug_en.pdf?utm_source=openai))\n\n   If Secure Boot is greyed out or you can\u2019t enable/disable it, then check what\u2019s called the **Platform Mode**. It must be set to *User Mode* for Secure Boot to actually validate/non-validate signatures normally. Go to \u201cRestore Factory Keys\u201d if the system is stuck in \u201cSetup Mode.\u201d([support.lenovo.com](https://support.lenovo.com/us/en/solutions/ht515493?utm_source=openai))\n\n3. *Boot Priority / Boot Order*  \n   Navigate to **Startup \u2192 Boot**. You\u2019ll find \u201cBoot Priority Order.\u201d Make sure your USB drive is listed there (look for \u201cUSB HDD\u201d, \u201cUSB FDD\u201d, or a similar USB-named item). Select it as first if needed, then press **F10** to save and exit.([download.lenovo.com](https://download.lenovo.com/pccbbs/mobiles_pdf/tp_x9_15p_gen1_ug_en.pdf?utm_source=openai))\n\n   Also check that the F12 boot menu option or \u201cBoot device list\u201d is enabled so you can use F12 (or Fn+F12) during startup to pick the USB directly if you don\u2019t want to alter the main boot order.([itechguides.com](https://www.itechguides.com/how-to-enable-usb-in-bios-lenovo-boot-drives-f12-and-always-on-usb/?utm_source=openai))\n\n4. *USB drive format and compatibility*  \n\n   \u2022 If booting in **UEFI mode** (recommended), your USB should be formatted **FAT32**, with a GPT partition table.  \n   \u2022 If your USB media is built for *Legacy* (BIOS) boot, then use NTFS and MBR format.([download.lenovo.com](https://download.lenovo.com/pccbbs/mobiles_pdf/x9_15_gen1_ug_en.pdf?utm_source=openai))\n\n   Be aware \u2014 on this ThinkPad model, Legacy or CSM support might be restricted or crippled when Secure Boot is active or if firmware settings lock down support. Disabling Secure Boot temporarily can help test.([download.lenovo.com](https://download.lenovo.com/pccbbs/mobiles_pdf/tp_x9_15p_gen1_ug_en.pdf?utm_source=openai))\n\n5. *Possibly use a different USB port*  \n   This model has both USB-A and USB-C/Thunderbolt ports. Sometimes older USB-A ports are more reliably supported for booting. Also, try re-plugging the drive, or using a different USB drive, in case the drive or port has failure or compatibility issues.([download.lenovo.com](https://download.lenovo.com/manual/thinkpad_x9_15p/user_guide/en/Frequently_asked_questions.html?utm_source=openai))\n\n6. *Update BIOS / UEFI firmware*  \n   Lenovo may have released updates that improve USB boot compatibility or fix bugs around Secure Boot / USB detection. Make sure you're running the latest UEFI version.([download.lenovo.com](https://download.lenovo.com/manual/thinkpad_x9_15/user_guide/en/Frequently_asked_questions.html?utm_source=openai))\n\n---\n\n## If Booting Still Fails: Common Culprits\n\n- **Secure Boot is blocking your USB** because the boot media isn\u2019t signed with keys recognized by the firmware.\n- **Your USB wasn\u2019t formatted or built correctly**: wrong filesystem, wrong partition style, missing bootloader, etc.\n- **USB boot option is disabled, hidden, or restricted** by UEFI settings \u2014 either via Secure Boot or corporate/firmware policy.\n- **Fast Boot or equivalent features** might be skipping USB initialization, making the drive invisible at boot time.\n- **Hardware problem** with USB port or drive itself.\n\n---\n\nIf you want, I can walk you through making a bootable USB that works reliably with this model (Windows installers, Linux, etc.), with step-by-step commands or tools. Would you prefer that?"
